The design of solar cells with a bulk heterojunction is one of the most promising areas in renewable energy sources. Acceptor dopants with suitable physical characteristics are desirable components for ternary organic solar cells with cascade charge transfer. In this Short Note, 2-(4H-indeno[2,1-d][1,2,3]thiadiazol-4-ylidene)-1H-indene-1,3(2H)-dione was prepared by thionation of [1,2′-biindenylidene]-1′,3,3′(2H)-trione with Lawesson’s reagent in refluxing benzene. The structure of newly synthesized compound was strictly confirmed by spectral methods. The obtained optical and electrochemical properties make this compound a promising candidate for use in ternary organic solar cells.
