Polymer thin films that emit and absorb circularly polarised light have been demonstrated with the promise of achieving important technological advances; from efficient, high-performance displays, to 3D imaging and all-organic spintronic devices. However, the origin of the large chiroptical effects in such films has, until now, remained elusive. We investigate the emergence of such phenomena in achiral polymers blended with a chiral small-molecule additive (1-aza[6]helicene) and intrinsicallyChinese
发射和吸收圆偏振光的聚合物薄膜已被证明有望实现重要的技术进步；从高效、高性能的显示器，到3D成像和全有机自旋电子器件。然而，到目前为止，这种薄膜中大的手性光学效应的起源仍然是难以捉摸的。我们研究了与手性小分子添加剂（1-氮杂[6]螺旋烯）混合的非手性聚合物中出现的这种现象，并对其本质进行了分析
