4,7-DIBROMO-SUBSTITUTED 2,1,3-BENZOTHIA(SELENA,OXA)DIAZOLES AND [1,2,5]THIA(SELENA)DIAZOLO[3,4-c]PYRIDINES AS BUILDING BLOCKS IN SOLAR CELLS COMPONENTS

Abstract


2,1,3-Benzothia(selena,oxa)diazoles and [1,2,5]thia(selena)diazolo[3,4-c]pyridines are important building blocks in dye-sensitized solar cells. This microreview summarizes synthesis of their dibromo derivatives and conversion to dye-sensitized solar cell components by cross-coupling reactions and copolymerization.

Keywords
