Circularly polarized luminescence (CPL) has significant potential in numerous fields, including three-dimensional displays, medical diagnostic imaging, information encryption, and quantum computing. In this study, a pair of novel chiral copper (I) iodine complex scintillators, namely R/S- (Me3-3-AQ) Cu3I5·CH3CNn (R/S-1, R/S- (Me3-AQ) = R/S-3- (methyl) -3-aminoquinuclidine), were successfully synthesized and characterized. Experimental results showed that the chiral copper (I) iodine complexes (R/S-1) had high photoluminescence quantum yields (PLQYs) of 89. 84% and 91. 09%, and obvious CPL with asymmetry factors (glum) of +1. 93 × 10-3 and -1. 65 × 10-3, respectively. Flexible films were prepared based on R/S-1, and a higher resolution of 16. 6 lp/mm was obtained. These studies offer valuable insights for the future development of chiral copper (I) iodine cluster complex scintillator materials.
