Abstract

It has been established that both racemic and homochiral forms of a diaryl-substituted dibenzo[7]helicene exhibit reversible mechanochromic luminescence. The racemic and homochiral crystals of this helicene possessed different packing structures with different emission colors. Upon mechanical stimulation, both crystals were transformed into amorphous powders that exhibit similar emission colors.
