Lifetime-tunable circularly polarized luminescent system based on triplet-to-singlet Förster resonance energy transfer
Circularly polarized luminescence (CPL) materials have received widespread attention due to their remarkable performance and broad applications. However, current CPL material research primarily focuses on tunable color, intensity, and reversibility. Constructing CPL with adjustable lifetime remains a significant challenge. Herein, a series of CPL polymeric materials with tunable lifetime were obtained by employing phosphorescent terephthalic acid and chiral organic small molecule R/S-BNAF (a luminescent binaphthol derivative) to copolymerize with acrylamide in different ratios. It was verified that this performance results from the different energy transfer efficiency between luminophores with varying ratios of the monomers for copolymerization. This strategy to realize CPL with tunable lifetime by modulating the energy transfer efficiency will provide a new perspective to broaden the applications of CPL materials.
