Abstract

New unsymmetrical diarylethenes were synthesized and their photochromic and fluorescent properties are tailored by Cu²⁺ and CN⁻ coordinations. A novel molecular logic keypad lock is constructed based on the fluorescence emission changes by the inputs of UV/visible irradiation, Cu²⁺ and CN⁻.
