Abstract

We report a simple design and synthesis of a donor-acceptor tetraphenylethene-naphthalimide (TPE-NI) dyad, in which TPE acts both as an electron-donor for intramolecular charge transfer (ICT) and activator for aggregation induced emission (AIE). Strong solvent-dependent photoluminescence covering almost the whole visible spectrum and AIE in its nanoparticle state compared to its solution state are demonstrated.

摘要

我们报告了一种供体-受体四苯乙烯-萘酰亚胺（TPE-NI）二聚体的简单设计和合成，其中 TPE 既作为分子内电荷转移（ICT）的供体，又作为聚集诱导发射（AIE）的激活剂。与溶液状态相比，其纳米颗粒状态下具有强烈的溶剂依赖性的全可见光谱范围的光致发光和 AIE。
