Abstract
AbstractIn this study, a pair of chiral copper(I) cluster‐assembled materials (R/S‐2) was prepared, exhibiting unique photo‐response characteristics with a concentration‐wavelength correlation property in DMSO solution. By the combination of R/S‐2 with a polymethyl methacrylate (PMMA) matrix, the first photo‐activated circularly polarized luminescence (CPL) film was developed, the CPL signal (glum=9×10−3) of which could be induced by UV light irradiation. Moreover, the film exhibited a reversible photo‐response and extremely good fatigue resistance. Mechanism study revealed that the photo‐response properties of the R/S‐2 solution and film are attributed to the aggregation‐induced emission (AIE) characteristics of R/S‐2 and a photo‐induced deoxygenation process. This study enriches the types of luminescent cluster‐assembled molecules and provides a new strategy for the construction of metal cluster‐based stimuli‐responsive composite materials.
