Choi, Min Hee published the artcileEffect of side chains on solubility and morphology of poly(benzodithiohene-alt-alkylbithiophene) in organic photovoltaics, Recommanded Product: 2-Bromo-3-(2-ethylhexyl)thiophene, the publication is Journal of Industrial and Engineering Chemistry (Amsterdam, Netherlands) (2015), 120-128, database is CAplus.
It was reported that the side chains play especially an important role in enhancing phys. properties and energy levels. Polythiophene based on benzodithiophene has excellent carrier mobility, but high HOMO level. We synthesized polythiophenes, PBDTBiTh(2EH) and PBDTBiTh(12C), were polymerized using the Stille coupling reaction and had thiophene with a 2-ethylhexyl or n-dodecyl side chain. Upon introducing the 2-ethylhexyl side chain, the absorption coefficients of the monomers and polymers were enhanced. Also, the edge-on orientation was fortified and the HOMO level was decreased to -5.37 eV. PBDTBiTh(2EH) showed a power conversion efficiency (PCE) of 2.1%, which was double that of PBDTBiTh(12C).
