- Practical Synthesis of Vinyl-Substituted p-Phenylenevinylene Oligomers and Their Triethoxysilyl Derivatives
-
Luminescent semiconducting organic compounds are widely used as active layers in electro-optical devices. Apart from conjugated polymers, monodisperse oligomers also represent attractive materials. The synthesis of stilbenoid oligomers with polymerizable

- Phase transformation and self-assembly behavior of supramolecular rod-comb block copolymers
-
We investigated the self-assembly behavior of a series of supramolecular rod-comb block copolymer complexes made by the hybridization of rod-coil diblock copolymers of poly (2,5-di(2-ethylhexyloxy)-1,4-phenylene vinylene)-b-poly(2- vinyl pyridine) (PPV-b-

- Push-pull chromophore with phenylene and thiophene as conjugation bridge for electro-optic applications
-
We designed and synthesized a push-pull type chromophore (PT-TCF) containing phenylene and thiophene ring as a conjugation bridge. Bulky alkyl chain was substituted into the phenylene bridge to minimize the intermolecular interaction among the neighbor mo

- Structure and thermodynamics of weakly segregated rod-coil block copolymers
-
The self-assembly of a series of monodisperse rod-coil block copolymers is studied in the weak segregation limit. This unusual weakly segregated system consists of polyisoprene (PI) coil blocks and poly(alkoxyphenylene vinylene) (PPV) rod blocks solubiliz

- Donor - Acceptor diblock copolymers based on PPV and C60: Synthesis, thermal properties, and morphology
-
An improved synthetic method to nitroxide end-capped poly(p- phenylenevinylene)s is presented. The nitroxide-functionalized PPVs are extended with a second coillike block by employing them as macroinitiators in a nitroxide-mediated radical polymerization (NMRP) of monomers like styrene, 4-chloromethylstyrene, 4-vinylpyridine, and n-butyl acrylate. The observed thermotropic properties and morphology of films based on the rod-coil diblock copolymers are identified and described. Some of the block copolymers are subsequently subjected to a coupling with C60 to incorporate electron-accepting properties into these PPV-based diblock copolymers. For this, a statistical copolymer built from styrene and azidomethylstyrene was used as the second coillike block, making it possible to adjust the built-in ratio of C60. The morphology and thermotropic properties of films prepared with these diblock copolymers are investigated.
