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.
