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.

The first application of the diselenolodiselenole (C4Se4) heterocycle as an active organic field effect transistor materials is demonstrated here. C4Se4 derivatives (2a-2d) were obtained by using a newly developed straightforward diselenocyclization protocol, which includes the reaction of diynes with selenium powder at elevated temperature. C4Se4 derivatives exhibit strong donor characteristics and planar structure (except 2d).
