摘要：How to efficiently design and synthesize multifunctional molecules is particularly challenging. In this presentation, we devote to constructing a kind of simple structures with composite functionalities through straightforward preparation. Starting from common commercially available materials, the titled cis/trans-tetraarylethenes can be conveniently obtained by a one-pot process under mild conditions. The different configurations were confirmed by H-1 NMR and single crystal data analysis. The trans-tetraarylethenes could be converted into cis-forms not only by photoirradiation but also by microwave irradiation, which provided us a new choice for isomeric conversion, especially in relation to light sensitivity. Results show that all the hybrid cis/trans-isomers performed switchable fluorescence and reversible photochromism in solution, PMMA film, solid powder, and single crystal. Moreover, these hybrid trans-tetraarylethenes could be utilized as photoswitchable media to tune the behavior of aggregation-induced emission (AIE) and aggregation-caused quenching (ACQ). These versatile properties are favorable for the potential applications in fluorescent photoswitches, nondestructive readout, and logic gates. We hope that our design strategy could provide a new protocol for constructing a kind of multifunctional molecules based some simple structure and convenient synthetic procedures.
