Functionalized liquid-crystalline donor-acceptor triple compounds containing azobenzene for optical storage
Communication: A non-symmetric, three-component, charge-transfer molecule is introduced and experimental results on structure formation and optical storage are presented. The storage process takes place via the isomerization of the functional azo group in a transparent film. The Figure shows the molecule, consisting of a disc-like pentaalkynylbenzene donor group linked to a flat nitrofluorenone acceptor by a rod-like chromophoric azo moiety.
