摘要

通过将非手性荧光染料掺杂到手性聚合物基体中，可以诱导圆极化发光。本研究展示了手性聚l -乳酸（PLLA）与荧光染料9,10-双（苯乙基）蒽（BPEA）的超分子自组装，形成微球生成cpld。随着BPEA浓度的增加，荧光颜色从蓝色变为绿色和红色，表明形成了BPEA二聚体和j聚集体。当BPEA/PLLA比为0.1时，微球悬浮液的发光不对称系数（glum）最高，为3.1 × 10−2。

Induced blue, green, and red-colour circularly polarized luminescence from single dye-doped homochiral poly(lactic acid) microspheres†

Circularly polarized luminescence (CPL) can be induced by doping an achiral fluorescent dye into a chiral polymer matrix. Here, we demonstrate the supramolecular self-assembly of chiral poly(L-lactic acid) (PLLA) with the fluorescent dye, 9,10-bis(phenylethynyl)anthracene (BPEA), forming microspheres that generate CPL. As the BPEA concentration increases, the fluorescent colour shifts from blue to green and red, suggesting the formation of BPEA dimers and J-aggregates. The highest luminescent dissymmetry factor (g_lum) of 3.1 × 10⁻² was obtained from the microsphere suspension at the BPEA/PLLA ratio of 0.1.
