AI Article Synopsis
- A study developed chiral copper(I) cluster-assembled materials (R/S-2) that display unique photo-response traits in a DMSO solution, linked to concentration and wavelength.
- Combined with a polymethyl methacrylate (PMMA) matrix, they created the first photo-activated circularly polarized luminescence (CPL) film, which emits a strong CPL signal when exposed to UV light.
- The film demonstrates a reversible photo-response and excellent fatigue resistance, with underlying mechanisms involving aggregation-induced emission (AIE) and a photo-induced deoxygenation process.
Article Abstract
In 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 (g =9×10 ) 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.
