Hetarylbenzene compounds

A compound consisting of three aromatic moieties respectively bonded to a methyl carbocation, and a counterion; wherein each of the three aromatic moieties is optionally substituted with an electron-donating group, at least one of the three aromatic moieties is bonded to a metal complex moiety, either directly or through a linker, and the methyl carbocation, the aromatic moieties, the metal complex moiety, and the linker form a conjugated system.

Organometallic compounds

The synthesis of a nonlinear chromophoric co-monomer 3,5-diamino-4'-nitrodiphenylamine and use as a reactive component in combination with a bismaleimide monomer in a NLO-active polyimide matrix is disclosed. After concurrent corona or contact poling and thermal polymerization, thin films of these chromophoric polyimides exhibit high second harmonic generation efficiencies and high DSC-determined glass transition temperatures. These poled polyimides also exhibit excellent SHG temporal stability, retaining 85-90% of the initial second harmonic efficiency after more than one month in air at 85.degree. C.
