In recent years, fluorescent functional materials with aggregation-induced emission (AIE) properties have evolved to be one of the most attractive topics within chemistry and materials science. In particular, discrete TPE-based metallacycles or metallacages through coordination-driven self-assembly have proven to be novel scaffolds to construct various fluorescent materials with light-emitting characteristics. Herein, we report the preparation of a new family of discrete, TPE-based supra-amphiphilic metallacycles decorated with three PNIPAAM arms through combination of an exo-functionalization strategy and post-assembly polymerization. The obtained supra-amphiphilic organometallic species could spontaneously self-assemble into fluorescent nanoparticles in water. Moreover, by taking advantages of both AIE property and good biocompatibility of the obtained TPE-based supra-amphiphilic metallosupramolecular structure, its potential application in cell imaging was investigated.

甲四苯基（TPE）为基础的超两亲性有机铂（II）金属环和其自组装行为†

近年来，具有聚集诱导发射（AIE）特性的荧光功能材料已发展成为化学和材料科学领域中最有吸引力的主题之一。特别地，已经证明通过配位驱动的自组装的离散的基于TPE的金属环或金属环是构造具有发光特性的各种荧光材料的新型支架。在本文中，我们报告了一个新的离散家族，基于TPE的超两亲金属单分子环的制备，这些分子通过一个exo的组合装饰着三个PNIPAAM臂-官能化策略和组装后聚合。所获得的超两亲性有机金属物种可以在水中自发地自组装成荧光纳米颗粒。此外，通过利用获得的TPE基超两亲性金属超分子结构的AIE性能和良好的生物相容性，研究了其在细胞成像中的潜在应用。
