Development of a New Multiple Stimuli-Responsive Fluorescent Material Using the Minus Strategy Based on the Structure of Tetraphenyl-1,3-butadiene

In this study, we
designed and synthesized a new class of aggregation-induced
emission luminogens, which was inspired and developed from the structure
of tetraphenyl-1,3-butadienes derivative (TPB-1) through the minus
strategy by removing one of the phenyl groups. Among them, L1 and L4 exhibited an aggregation-induced emission effect
and multistimuli-responsive chromic behavior. Moreover, two types
of single crystals of L1 were obtained, and their different
emission behaviors were elucidated clearly by analyzing the single-crystal
data.

在本研究中，我们设计并合成了新一类聚集诱导发光的发光体，该发光体源自于四苯基-1,3-丁二烯衍生物（TPB-1）的结构，通过减法策略移除其中一个苯基团而启发与开发。其中，L1和L4表现出聚集诱导发光效应和多刺激响应的铬变行为。此外，还获得了L1的两种单晶类型，通过分析单晶数据，其不同的发光行为得以明确阐释。
