New thiophene-phenylene-thiophene acceptor random conjugated copolymers for optoelectronic applications

Investigations of New Low Gap Conjugated Compounds Based on Thiophene-Phenylene as Solar Cells Materials

The research in new organic π-conjugated molecules with specific properties has become one of the most interesting topics in fields of materials chemistry. These materials are promising for optoelectronic device technology such as solar cells. On the other hand, the use of low band gap materials is a viable method for better harvesting of the solar spectrum and increasing its efficiency. The co...

investigations of new low gap conjugated compounds based on thiophene-phenylene as solar cells materials

Conformational analysis (ab initio HF/3-21G*) and optical properties of poly(thiophene-phenylene-thiophene) (PTPT)

The optical properties of two series of thiophene-based polymers are interpreted by torsion analysis. When approached by the calculated HOMO/LUMO energy gaps of model molecules, the wavelength shifts from solutions to films are reasonable in cyclohexyl-substituted series but not in hexyl-substituted series, indicating that solid packing force plays a more important role in the former than in th...

Design, Synthesis, Characterization and Use of Random Conjugated Copolymers for Optoelectronic Applications

We report the synthesis and the optoelectronic characterization of a new family of random conjugated copolymers based on 9,9-bisalkylfluorene, thiophene and benzothiadiazole monomers unit synthesized by a palladiumcatalyzed Suzuki cross-coupling reaction. The photophysical, thermal, electrochemical properties were investigated. The electronic structures of the copolymers were simulated via quan...
