近日,深圳大学杨楚罗教授、李凯副教授团队采用同时具有良好平面性和强给电子能力的给体,结合平面结构的受体单元,调控分子内非共价相互作用,实现了较高效率的红光和深红光 TSCT-TADF 分子。 该工作以氧桥连三苯胺(TPXZ)作为电子给体,设计了两...
本发明属于发光与显示,具体涉及一种二氰基苊并吡嗪tsct-tadf近红外发光材料及其应用。 背景技术: 1、有机发光二极管具有清晰度高、质量轻、可绕曲等优异性能,目前已广泛应用于显示,市场潜力巨大。高效oleds的提升核心在于新型发光材料的更新换代。传统荧光材料构筑的oleds中,有75%的三线态激子通常因跃迁禁阻而不发光...
Donor–Acceptor MOF Enabling Efficient Electrochemiluminescence Based on TSCT-TADFdoi:10.1021/acs.jpclett.4c01967Electrochemiluminescence (ECL) is an extensively studied luminescence technique recognized for its efficacy in investigating surface energy states. Effective utilization of ECL to explore and ...
Interestingly, it was observed that RISC in AC-BO and one derivative, AC-BCO, occurs predominantly via the T2 state rather than the typical T1 state (3LEB, where B denotes the fluorene bridge), distinguishing it from conventional TSCT-TADF compounds, where RISC typically involves transitions ...
