The effect of axial and helical twisting on the circularly polarized luminescence of acenes was studied both experimentally and computationally, using four series of tethered twisted acenes. We find that the combination of axial and helical chirality yields the highest anisotropy factors, and that the ratio between the absorption and emission anisotropy factors is an intrinsic property for twistacenes.
我们通过四个系列的连接扭曲并苯分子，从实验和计算两个方面研究了轴向和螺旋扭曲对并苯圆偏振发光的影响。我们发现，轴向和螺旋手性的组合产生了最高的各向异性因子，并且吸收和发射各向异性因子之间的比值是扭曲并苯的固有性质。
