A hierarchical self-assembly in comb-shaped supramolecules of conjugated rodlike polymers is reported. The supramolecules consist of poly(2,5-pyridinediyl), aciddopants, and hydrogen bonded alkyl side chains. A thermotropic smectic state with an exce...

The reactions of primary and secondary amines with 7,7,8,8-tetracyano-p-quinodimethane(TCNQ) lead to mono- and di-substituted adducts. Fluorescence emission has been observed for several of these compounds. The luminescence property of the TCNQ adduc... Read More about Matrix dependence of light emission from TCNQ adducts.
