In this study, a molecular design concept of inhibited pyramidal inversion for the amino auxochrome is proposed. Dyes 3a-3d are designed and synthesized by introducing 7-azabicyclo[2.2.1]heptane (pyramidal inversion energy barrier 14.1 kcal mol−1) as auxochrome into the 1,8-naphthalimide fluorophore framework. Dye 3a exhibits a high fluorescence quantum yield (Φ) of 0.963 in 1,4-dioxane, maintains 0.746 in DMSO, and still achieves 0.284 in H2O, and dyes 3b-3d demonstrate analogous solvent-dependent behavior. Density functional theory (DFT) calculations reveal that the configuration of 3a remains nearly unchanged in both the ground and excited states. Remarkably, dyes 3a-3d display bright solid-state fluorescence with photoluminescence quantum yields (PLQY) of 0.674, 0.596, 0.813, and 0.924, respectively. Single-crystal X-ray analysis of 3a shows parallel molecular packing with an interplanar distance of 3.628 Å and an intramolecular auxochrome-fluorophore dihedral angle of 83.35°, which collectively mitigate π–π stacking interactions. When dispersed in ethylene-vinyl acetate (EVA) matrix, dyes 3a-3d demonstrate PLQY values exceeding 0.947. These results show that incorporating 7-azabicyclo[2.2.1]heptane as auxochrome in 1,8-naphthalimide-based fluorophores effectively enhances the luminescent properties of the dyes in solution, solid, and EVA-film states.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 29","pages":""},"PeriodicalIF":7.2,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145284716","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, despite numerous studies on various D-A radical dyads, their structure-property relationship including carbazole-TTM remains elusive. Here, a series of TTM radical acceptor coupled with methyl-modified carbazole donor is synthesized and used as a model system to investigate the influence of the D-A dihedral angle, known as a primal parameter of luminescent closed-shell D-A compounds, on the photophysical properties of D-A radicals. The results reveal that the dihedral angle tunes the hybridization of locally excited transitions and intramolecular charge transfer (CT) transitions. The larger angles lead to an enhancement of the CT character in the excited state, which suppresses radiative decay due to decreased donor–acceptor orbital overlap and increases non-radiative decay according to the energy-gap law, leading to reduced photoluminescence quantum yields. Furthermore, the increased CT character in the excited state bypasses photocyclization of the TTM moiety and improves photostability. These findings indicate that D-A dihedral angle plays a crucial role in balancing the luminescence efficiency and photostability of the organic luminescent radicals.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 29","pages":""},"PeriodicalIF":7.2,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145284714","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The nanoparticle-on-slit (NPoS) or nanoparticle-in-groove (NPiG) antenna is a recently introduced dual-band structure with independently tunable resonances at mid-infrared and visible wavelengths. It has been used to enhance sum- and difference-frequency generation from optimally located molecules by an estimated 1013-fold. However, theoretical understanding of its eigenmodes remains limited, constraining further optimization and broader application. Here, the quasi-normal modes (QNMs) supported by NPoS structures are investigated, analyzing how both near-field (giant photonic density of states) and far-field (radiation pattern) characteristics influence upconversion. Tuning strategies are identified to adjust visible and mid-infrared resonances independently while maintaining strong near-field mode overlap, which governs the efficiency of nonlinear processes. Additionally, mode analysis reveals a previously unexplored resonance offering greater field enhancement and superior spatial mode overlap with the mid-infrared field, potentially improving upconversion efficiency fivefold compared with the existing results. This work helps to rationalize and optimize the enhancement of nonlinear effects across a wide spectral range using a flexible and experimentally attractive nanoplasmonic platform.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 29","pages":""},"PeriodicalIF":7.2,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/adom.202501674","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145284715","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, despite achieving a relatively high kRISC of over 106 s−1, the operational stability of blue TADF-OLEDs is still unsatisfactory. On the other hand, another critical issue originates from intermolecular interactions during electrical excitation, leading to unwanted degradation events such as exciton-polaron annihilation. Thus, “shielding” substituents are incorporated to protect the emitter molecules from unwanted interactions. To address this issue, six TADF emitters having different bulky shielding substituents: 1Ph, 2Ph, 3Ph, 4Ph, CzPh, and m2PhCz are designed, and confirmed that the OLED stability is extended by introducing shielding substituents.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 29","pages":""},"PeriodicalIF":7.2,"publicationDate":"2025-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145284948","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In such dye-focused methodologies, the matrix plays a minimal role beyond hosting the emitters. However, this strategy can be unpredictable due to the complexity of modifying dye photophysics with precision. In the work here presented, a matrix-driven approach to WLE is introduced, where the properties of the polymeric host are leveraged to regulate light emission. By adjusting the composition of the polymer network with variation in monomers and cross-linkers, it is possible to control the spatial arrangement and interaction of two dyes, enabling effective color mixing. The system employs readily available monomers, 2-hydroxyethyl methacrylate (HEMA) and poly(ethylene glycol) dimethacrylate (PEGDMA), along with two simple, synthetically accessible dyes: a pyridinium salt and a pyrylium derivative. The resulting hydrogel-based films emit white light with Commission Internationale de l'Éclairage (CIE) chromaticity coordinates at (0.30, 0.33) and a high photoluminescence quantum yield of 0.51. The films are highly transparent, flexible, and suitable for back-illumination, making them excellent candidates for integration into next-generation optoelectronic platforms, such as bendable lighting elements, transparent displays, and wearable light sources. This strategy highlights the untapped potential of polymer matrices in fine-tuning emissive behavior.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 27","pages":""},"PeriodicalIF":7.2,"publicationDate":"2025-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/adom.202501380","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145111370","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The design and development of aromatic imide acceptors are comprehensively outlined. Their structural configurations and energy level characteristics, along with the progress of corresponding TADF molecules, are examined and categorized by the ring size of the imide group (including five-, six-, and seven-membered aromatic cyclic imides). Subsequently, the design strategies for TADF molecules based on aromatic amides are discussed, revealing that the N-R-N-phenylbenzamide framework is the most common structural motif among reported emitters. Finally, an in-depth analysis of the structural designs of aromatic imide/amide molecules that achieved high external quantum efficiencies across various emission wavelength ranges is conducted.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 29","pages":""},"PeriodicalIF":7.2,"publicationDate":"2025-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145284951","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, using particles that display sharp features, such as gold nanostars or bipyramids, can be challenging because plasmonic heating involved in the printing process can lead to tip blunting and melting. This adversely affects the performance of these particles for spectroscopic or catalytic applications. Therefore, strategies need to be implemented to avoid thermal reshaping of complex-shaped nanoparticles either by minimizing plasmonic heating or by dissipating heat away from the particles. Here, an alternative view is proposed. Rather than avoiding plasmonic heating, it is demonstrated that optothermal printing can be leveraged to transform gold nanorods into ellipsoidal or lemon-shaped particles with sharper tips and enhanced local electromagnetic field intensities compared to the initial rods. The potential of these “nano-lemons” for spectroscopic applications is exemplified through surface enhanced Raman scattering measurements of azobenzene photoisomerization within supported photolipid bilayer membranes.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 29","pages":""},"PeriodicalIF":7.2,"publicationDate":"2025-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145284947","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is found that alloys always display stronger nonlinearities compared to pristine TMDs. In addition, by comparing the resonant energies of SHG and TP-PL, a non-monotonic change of the energy difference between the 1s and 2p states of the A exciton, pointing toward the possibility of tuning the exciton binding energy by alloying and material composition, is found. Finally, layer-dependent SHG and TP-PL, which show an alternate broken/preserved space inversion symmetry for odd/even number of layers and a transition from indirect to direct bandgap when thinning down the layered samples to the monolayer limit, is reported.
