Small isomeric push-pull chromophores based on thienothiophenes with tunable optical (non)linearities

Fourteen new D-π-A push-pull chromophores based on two isomeric thienothiophene donors and seven acceptors of various electronic natures have been designed and conveniently synthesized. In contrast to known thienothiophene push-pull molecules, the prepared small chromophores proved to be organic materials with easily tunable thermal, electrochemical and (non)linear optical properties. It has also been shown that small structural variation may result in significantly improved/varied fundamental properties. Very detailed structure-property relationships were elucidated within the systematically developed series of push-pull molecules, which may serve as a useful guide in designing new D-π-A molecules based on fused thiophene scaffolds.

D/A cruciform bithiophene chromophores as potential molecular scaffolds for optoelectronic applications

The development of a one pot, regiocontrolled, three-component reaction for the synthesis of thieno[2,3-c]pyrroles

A three-component reaction has been developed that allows the regioselective synthesis of thieno[2,3-c]pyrroles. The reaction is based on the ability of 2-acetyl-3-thiophenecarboxaldehyde to react with amine and thiol nucleophiles to produce the corresponding tri-substituted thieno[2,3-c]pyrroles, with water as the only by-product. The developed reaction expands the range of synthetically accessible, tri-substituted thieno[2,3-c]pyrroles. The Royal Society of Chemistry 2013.
