Mei, Jianguo published the artcileSynthesis of isoindigo-based oligothiophenes for molecular bulk heterojunction solar cells, Recommanded Product: 5,5′-Bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-2,2′-bithiophene, the publication is Organic Letters (2010), 12(4), 660-663, database is CAplus and MEDLINE.
Isoindigo, as a new electron acceptor unit for organic electronic materials, was integrated into two low-energy gap oligothiophenes. Optical and electrochem. studies of the newly synthesized oligomers demonstrate broad absorption through the visible spectrum, along with appropriate energy levels, as desired for light harvesting donors for organic solar cells when blended with [6,6]-phenyl-C61-butyric acid Me ester (PC60BM). Mol. heterojunction solar cells were fabricated using these oligomers and exhibit a power conversion efficiency up to 1.76% with a Voc of 0.74 V, Isc of 6.3 mA/cm2 and fill factor of 0.38.
