This paper presents a facile method for fabricating a thin-film sample with a high asymmetry value of induced circularly polarized luminescence (iCPL) (|g_lum| = 2.0 × 10^–3). The method involves mixing stereoregular poly(methyl methacrylate) (PMMA) and chiral chromophore (2,2,2-trifluoro-1-(9-anthryl)ethanol (TFAE)) to form a complex with a dynamic helical conformation of poly(methyl methacrylate) (PMMA) associated with TFAE via hydrogen bonding. This dynamic helical conformation can be stabilized by the stereocomplexation of a pair of stereoregular PMMA, where the TFAE is sandwiched between a double-helix isotactic PMMA and single-helix syndiotactic PMMA, resulting in a preferential one-handed helical conformation with a high value of iCPL from self-assembly.

凹槽锚驱动光学活性聚（甲基丙烯酸甲酯）立体复合物的圆偏振发光

本文介绍了一种制备具有高诱导圆偏振发光 (iCPL) 不对称值 (|g _lum | = 2.0 × 10 ^–3 ) 的薄膜样品的简便方法。该方法涉及将立构规整聚（甲基丙烯酸甲酯）（PMMA）和手性发色团（2,2,2-三氟-1-（9-蒽基）乙醇（TFAE））混合，形成具有聚（甲基）动态螺旋构象的复合物甲基丙烯酸酯）（PMMA）通过氢键与 TFAE 结合。这种动态螺旋构象可以通过一对立体规则 PMMA 的立体络合来稳定，其中 TFAE 夹在双螺旋全同立构 PMMA 和单螺旋间同立构 PMMA 之间，从而产生具有高值的优先单手螺旋构象来自自组装的 iCPL。
