基于松香D-A骨架TICT-AIE协同效应的双通道发射调控及性能研究OA
Dual-channel Emission Regulation and Performance Based on Synergistic Effect of TICT-AIE in Rosin D-A Skeleton
以脱氢松香酸为刚性骨架,通过引入三苯胺给体单元与萘酰亚胺受体单元,成功构筑了兼具TICT与AIE特性的新型发光衍生物A-TPA-N,依托混合溶剂荧光测试系统解析其发光机制,重点探究了差异化激发波长下的双通道发射行为,以及溶剂极性、聚集效应对LE态与ICT态发光的调控规律.此外,天然手性骨架成功诱导了圆偏振发光.本文为开发高性能天然生物手性发光材料提供了新策略,并且这类材料在显示和生物成像等领域具有潜在的应用价值.
In this study,a novel luminescent derivative A-TPA-N with both TICT and AIE properties was success‑fully constructed by introducing triphenylamine donor units and naphthalimide acceptor units into the rigid skeleton of dehydroabietic acid.The luminescence mechanism was analyzed by a mixed-solvent fluorescence testing system,with a focus on the dual-channel emission behavior under different excitation wavelengths,as well as the regulation rules of solvent polarity and aggregation effect on the LE state and ICT state luminescence.Moreover,the natural chi‑ral skeleton successfully induced circularly polarized luminescence.This work provides a new strategy for the devel‑opment of high-performance natural biochiral luminescent materials,and these materials have potential application value in fields such as display and bioimaging.
