摘要

A novel photochromic diarylethene dimer with a bis(benzylene)amine-linked naphthalimide unit was synthesized, and its photochemical properties were systematically studied. Upon irradiation with ultraviolet light, a singly-closed isomer and a fully-closed isomer were reversibly formed, which were confirmed by the results of Nuclear Magnetic Resonance spectroscopy (NMR) and High-Performance Liquid Chromatography (HPLC). Additionally, the diarylethene dimer could be used as a multi-addressable fluorescence switch when triggered by light, proton, and metal ions. Moreover, a logic circuit was constructed with the unimolecular platform by using the fluorescence intensity at 445 nm as output and appropriate combinational stimuli of UV light, Al3+, and EDTA as inputs.
