Simultaneous Optical Tuning of Reflection and Fluorescence in a Self-Organized Simple 3D Cubic Structure by α-cyanodiarylethene-based Chiral Fluorescence Photoswitches

A novel optically-tunable BPLC system enabled by an α -cyanodiarylethene fluorescence photoswitch is reported, in which the phototuning of both reflection and fluorescence of BPII with a self-organized simple 3D cubic structure is demonstrated.
