Fused thiophenes: An overview of the computational investigations

Computational investigations of fused thiophenes including not only thienothiophene, ditihienothiophene and thienoacene but also other thiophene-fused (hetero)-aromatic rings have been surveyed. The effect of the methods and basis sets applied on promising optoelectronic materials were elaborated. This brief review suggests the best method for the fused thiophenes to be B3LYP functional.
