ABSTRACT:
The present invention introduces a novel route toward microstructural orientation into organic films, using multiple hydrogen-bonding to self-assemble chromophore molecules into electro-optic films in a net polar orientation. High-quality, thick films (up to micrometers) with molecular net dipole orientations can be fabricated under vacuum in hours. The film microstructure is intrinsically acentric; and the orientation is robust.
