Solid additives play a vital role in this process, with 3D polyhedral or spherical molecules being ideal candidates due to their delocalized π-orbitals and omnidirectional charge transport. However, the application of classical fullerene derivatives as spherical additives is limited by their synthetic complicacy and poor solubility. Herein, the potential of 3D globally aromatic carboranyl cages as solid additives, specifically 1-amino-o-carborane (CB-NH2) and 1-carboxy-o-carborane (CB-COOH), is explored to fine-tune the film morphology and improve the performance of OSCs. These spherical molecules provide an extensive surface for hydrogen bonding interactions, which serve as the driving force for manipulating the vertical phase separation and active layer crystallinity. Remarkably, CB-NH2-processed devices with well-tuned morphology yield a remarkable power conversion efficiency of 19.48%, highlighting the effectiveness of 3D carboranyl additives on improving OSC performance. This work challenges the reliance on fullerene derivatives as spherical additives and offers new insights into the mechanisms by which 3D globally aromatic additives can achieve high performance in OSCs, emphasizing the significance of molecular engineering in the development of next-generation solar cell technology.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"34 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2024-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142670776","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, a novel design strategy is proposed for blue hot exciton (HE) materials, which involves utilizing a “cross” shaped molecular structure characterized by substantial steric hindrance and a highly twisted conformation. The unique cross-shaped molecular architecture with distinct “arms” enables flexible control over the excited state properties of the molecule, thereby facilitating precise modulation of high-lying triplet and low-lying singlet excited state energy levels. Furthermore, the 3D spatial configuration of the molecule effectively reduces close molecular packing, thereby minimizing the risk of material concentration quenching. The proof-of-concept HE emitters CN-PI and TP-PI exhibit non-π-π stacking configurations in single crystals, achieving high photoluminescence quantum yield (PLQY) values up to 51.3% and 46.5% in non-doped thin films, respectively, along with rapid radiation decay rates and reasonable distribution of Tm (m ≤ 5) and S1 states.

This study demonstrate that the strength of the intramolecular interaction between hypervalent antimony and the π-conjugated framework can be tuned with ligand structure, substituent effect, and oxidation number shifts of hypervalent antimony. In particular, the color changes represented by hypsochromic and bathochromic wavelength shifts of optical bands are achieved by the oxidative reaction of hypervalent antimony in the solid state.

Theoretical calculation and experimental investigations reveal that the d-band center of Cu atoms is significantly shifted upward when Cu doped into the (204) facet of bassanite compared to the (400) facet. A higher d-band center facilitates adsorption and activation between Cu and O2 through the formation of stronger d-π* orbital hybridization, resulting in increased ROS production.

To address these issues, a general strategy is presented in which the Cs2PdBr6 perovskite surface is coated with covalent organic framework (COF) to provide hybrid sensor materials that are highly sensitive to specific gases and demonstrate excellent stability under real-working conditions. The hybrid chemiresistors demonstrate high sensitivity and controllable selectivity toward NO2 or NH3 gases. Specifically, TAPB–PDA@Cs2PdBr6 achieves a detection limit of 10 ppb for NO2, the lowest value reported for a perovskite-based gas sensor, maintaining its performance after continuous exposure to ambient air for several weeks. In contrast, COF-5@Cs2PdBr6 shows high selectivity to NH3 and has a detection limit of 40 ppb.

Traditional absorbers, including metal- and carbon-based materials, often lack the flexibility required for such applications. In this work, a novel strategy is proposed for developing a flexible absorber by combining a conductive filler with a Schottky heterogeneous interface and a polymer network framework. Ti3C2Tx MXene is modified with ZnS via a low-temperature hydrothermal method, forming a Ti3C2Tx/ZnS composite. This composite is subsequently embedded in a copolymer matrix of polyvinyl alcohol (PVA) and acrylamide (AAm), dispersed in a binary water-glycerol solution. The Schottky interface between Ti3C2Tx and ZnS enhances electron transfer at the heterophase boundary, significantly improving interface polarisation. Simultaneously, interactions between water and glycerol restrict the rotation of polar molecules under external electromagnetic fields, optimising polarisation loss within the gel. Experimental results demonstrate that the Ti3C2Tx/ZnS gel achieves a minimum reflection loss (RLmin) of −43.76 dB at 8.79 GHz, with an effective absorption bandwidth (EAB) covering the entire X-band. Additionally, the gel exhibit exceptional stretchability, frost resistance, shape adaptability, and photothermal conversion properties.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"13 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2024-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142665392","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
