Abstract

The growth of H-bonded heteroaromatic films, which exhibited electo-optic responses, was investigated. The physical vapor deposition (PVD) method was used for the growth of the films, which were thermally stable, from heteroaromatic based chromophore assemblies. It was observed that the films grown by PVD exhibited good optical quality and microstructural regularity. supramolecular acentricity was also achieved without electric field poling, enforced by biomimetic heterocycle-hydroxycarbonyl head-to-tail hydrogen bonding. The results show that the films have the potential for application in electro-optic devices.
