Structural dependence of the optical properties of narrow band gap thiophene–thiadiazoloquinoxaline derivatives and their application in organic photovoltaic cells

Abstract

The structural causes for NIR absorption bands on new [1,2,5]thiadiazolo[3,4-g]quinoxaline derivatives were determined on the basis of DFT calculations and organic photovoltaic cells incorporating the new compounds were fabricated.
