Abstract
Planarized star-shaped oligothiophenes 1 have been synthesized by connecting short-chain oligothiophenes on a benzo[1,2-b:3,4-b‘:5,6-b‘ ‘]trithiophene central core. Their electrochemical and optical properties have been characterized by cyclic voltammetry and UV−visible spectroscopy, respectively. These results associated with theoretical calculations show the advantage of benzotrithiophene as a central core in terms of π-electron delocalization.Keywords
