) helical twisting power (β ) values (i.e., extent of chiral information transfer between dopant and host), with dispersion interactions and/or electron deficient aromatic units playing a crucial role in determining the value. The large change in β values upon E/Z photoswitching enabled us to devise multicolor, high contrast LC films that reflect across the UV to infrared light range.
