Diselenolodiselenole: a selenium containing fused heterocycle for conjugated systems

Abstract

The synthesis of new conjugated building blocks, diselenolodiselenole (C₄Se₄) derivatives, is described for the first time. The structural and optoelectronic properties of C₄Se₄-derivatives are tuned by varying end-capping aromatic substituents. In cyclic voltammetry, all C₄Se₄-derivatives show two reversible oxidation peaks.
