Authors


Abstract

Communication: A combined calculational and experimental study of methylated oligothiophenes allows the effects of different substitution patterns on the geometry, the inter-ring twist, and the conformational and optical properties of the oligomers, which have potential applications in molecular electronics and can be polymerized to polythiophenes, to be examined.
