ABSTRACT Tetraphenylethylene (TPE) related (supra)molecules have been intensively investigated due to their aggregation-induced emission (AIE) effect based on the restriction of intramolecular rotation (RIR). Meanwhile, boron-dipyrromethene (BODIPY) tends to emit intense fluorescence with high quantum yields. Herein, we combined TPE, BODIPY and terpyridine (TPY) into one system to study the emissive behaviour of organic building block as well as a self-assembled metallo-supramolecule. The TPY and BODIPY substituents with bulky sizes provide strong hindrance to restrict the rotation of the phenyl groups on TPE, leading to enhancement of emissive properties in both solution and aggregation states. Furthermore, the BODIPY-TPE-TPY ligand (L) was assembled with Zn (II) through coordination-driven self-assembly to form a cyclic dimer (D) with typical AIE characteristics. Graphical abstract

发射金属环与四苯基乙烯、BODIPY 和三联吡啶在一个系统中的自组装

摘要四苯基乙烯（TPE）相关（超）分子由于其基于分子内旋转（RIR）限制的聚集诱导发射（AIE）效应而得到深入研究。同时，硼二吡咯甲烯 (BODIPY) 倾向于以高量子产率发出强烈的荧光。在此，我们将 TPE、BODIPY 和三联吡啶 (TPY) 结合到一个系统中，以研究有机积木以及自组装金属超分子的发射行为。具有庞大尺寸的 TPY 和 BODIPY 取代基为限制 TPE 上苯基的旋转提供了强大的阻碍，从而增强了溶液和聚集状态下的发射性能。此外，BODIPY-TPE-TPY 配体 (L) 通过配位驱动的自组装与 Zn (II) 组装形成具有典型 AIE 特征的环状二聚体 (D)。图形概要
