Two pairs of D-A type AIE-active chiral dyes (R-/S-1 and R-/S-2) as chiral emitters doped into nematic liquid crystals (5CB, N-LCs) can form chiral nematic liquid crystals (N*-LCs) and regulate the amplified circularly polarized luminescence (CPL) signals. R-/S-2 with stronger D-A structure and more planar conformation could induce higher CPL response (glum = ±0.37) via the supramolecular self-assembly in N*-LCs system.

通过液晶系统,从DA型AIE活性手性发射体调节出放大的圆偏振发光。

两对DA型AIE活性手性染料(R- / S-1和R- / S-2)作为掺杂到向列液晶(5CB,N-LC)中的手性发射体,可以形成手性向列液晶(N *- LC)并调节放大的圆偏振发光(CPL)信号。具有更强DA结构和更多平面构象的R- / S-2可以通过N * -LCs系统中的超分子自组装诱导更高的CPL响应(glum =±0.37)。
