Sandwiched naphthyl carbazole: Inversion Circularly Polarized Luminescence based on a pull‐push electron valve strategy

AbstractInspired by circularly polarized luminescence (CPL), artificial CPL assembly has attracted intense attention. However, precise manipulation of chiral transfer from achiral and luminescent materials remains a formidable challenge. Two sandwiched carbazole and binaphthol derivatives composed of pyridine or trifluoride methyl benzene have been synthesized. Among R‐1 and R‐2, their spectra were found in the violet region, both in the solution and the film state. They exhibit the photoluminescence dissymmetry factors up to 1.4 × 10−3 for R‐2 and an opposite value of −5.6 × 10−4 for R‐1. Theoretical CPL and circular dichroism (CD) studies were in good agreement with the experimental data and deciphered their opposite signals by the transition electric and magnetic moment. Our study offers a strategy for studying the charge and chiral transfer.
