摘要：

Chiral emissive nematic liquid crystals (N*-LCs) can greatly amplify the circularly polarized luminescence (CPL) signals promoted by a highly regular spiral self-assembly in the LCs system. Naphthalimide (NI) derivatives have been assigned to be one of the most excellent chromophores for fluorescent materials. In this paper, a novel strategy is first developed to regulate full-color CPL behavior of N*-LCs through different chiral NI-based dyes. Chiral NI-based dyes are doped into nematic liquid crystals (E7, N-LCs) to form N*-LCs as CPL-active liquid crystal materials. Most interestingly, this kind of N*-LCs could emit standard white CPL signals (CIE coordinates: (0.31, 0.33)) by choosing the blue-red match of two chiral NI-based dyes at the appropriate ratio.
