Significant advances have been achieved in organic and inorganic materials; however, current enhancement strategies remain largely platform-specific and are not guided by a unified physical framework. To address this gap, this review introduces a three-factor physical model grounded in the theory of transition probability, thereby providing a consistent theoretical basis for understanding how electronic transitions are modulated across orbital, vibrational, and spin dimensions. Structure-mechanism-performance relationships are systematically examined in classic material platforms. In addition, the contributions of external-field enhancement mechanisms, such as plasmonic resonance, to spectral broadening and local-field enhancement are discussed. Based on clear mechanistic insight and targeted materials design, recent advances in integrating broad-absorbing materials into broadband photodetectors are highlighted, emphasizing their practical relevance. The review examines the three core challenges and mechanism-driven design strategies for high-performance broadband optoelectronic systems, providing an instructive outlook for future advancements.\u0000</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":773,"journal":{"name":"Science China Materials","volume":"68 9","pages":"3171 - 3187"},"PeriodicalIF":7.4,"publicationDate":"2025-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144924437","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 this work, two novel borates containing distinct assembly modes of [B₃O₇] groups, Li₂Rb₂BaB₁₈O₃₀ (LRBBO) and K_0.7Rb_1.3BaB₆O₁₁ (KRBBO), were designed and synthesized based on the dimension reduction strategy induced by cation modification using LiB₃O₅ as the parent structure.

Taking advantage of the solution processability of organic semiconductors, solution self-assembly OSSC arrays hold great potential for achieving cost-effective manufacturing of large-area and flexible electronics. While the rational design of molecular building blocks for regulating crystal growth has been achieved, the fundamental principles of molecular structure design for one-dimensional (1D) crystalline nanostructures and the impact of intermolecular interactions in molecular self-assembly remain unclear, limiting the practical application of the solution self-assembly. Drawing inspiration from the concave-convex packing preferences of bowl-shaped polyaromatic hydrocarbons, we propose an innovative molecular engineering strategy for hetero-buckybowl trichalcogenasumanenes to direct the self-assembly of OSSC arrays. The distinctive molecular architecture of trichalcogenasumanenes promotes the formation of 1D crystal arrays via directional concave-convex π-π interactions while effectively suppressing intercolumnar coupling, enhancing structural anisotropy and charge transport properties. Accordingly, the centimeter-sized OSSC arrays are obtained on various substrates via solution self-assembly. Furthermore, high-performance organic field-effect transistors (OFETs) based on these OSSC arrays demonstrate mobility values up to 0.89 cm² V⁻¹ s⁻¹ with small device-to-device variation, superior to previous buckybowl-based devices. This molecular engineering strategy significantly enhances crystallinity and uniformity, providing a pathway for high-performance, large-area organic electronics.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":773,"journal":{"name":"Science China Materials","volume":"68 10","pages":"3566 - 3573"},"PeriodicalIF":7.4,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144924431","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}
