Synthesis of novel diketopyrrolopyrrole-based dyes
摘要:
Three novel diketopyrrolopyrrole-based molecules for potential application in dye-sensitized solar cells are synthesized starting from a common and easily available key intermediate with a bis-thienyl diketopyrrolopyrrole structure. The synthetic sequence is based upon transition-metal catalyzed coupling reactions involving commercial boronic acid followed by condensation reactions with 2-cyanoacetic acid. Absorption and fluorescence spectra of the molecules are also reported.[GRAPHICS].

different donor (D) center of substituted benzodithiophene (BDT) in backbone, and the same acceptor (A) and bridged units of diketopyrrolopyrrole (DPP) and thienylenevinylenethiophene (TVT), respectively. Their thermal stability, crystallinity, film morphology and photoelectronic properties were primarily investigated. It was found the BDTx-2TVTDPP with 2,6-substituted BDT unit exhibited a pronouncedly

Four D-π-A sensitizers comprising a thienyl-diketopyrrolopyrrole (ThDPP) bridge were synthesized and tested in iodide/triiodide liquid electrolyte DSC devices. The dye series was strategically designed to develop a structure–property relationship. The best performing sensitizer utilized a phenyl-based anchor and triphenylamine donor (η = 5.03%).

A novel conjugated polymer of PBDT-TDPP-S was synthesized, which contains a donor unit of benzo[1,2-b:4,5-b′]dithiophene in main chain and an acceptor unit of diketopyrrolopyrrole in sidechain. This kind of side-chain donor–acceptor (D–A) polymer exhibited better solution processability, lower HOMO level (−5.34 eV), and more balanced carrier mobility relative to its corresponding main-chain D–A conjugated
合成了一种新型的PBDT-TDPP-S共轭聚合物,该聚合物在主链上含有苯并[1,2- b:4,5- b ']二噻吩的供体单元,在侧链上含有二酮吡咯并吡咯的受体单元。相对于其对应的主链D-A共轭聚合物,这种侧链供体-受体(DA)聚合物表现出更好的溶液加工性,更低的HOMO水平(−5.34 eV)和更平衡的载流子迁移率。使用PBDT-TDPP-S作为电子给体,使用[6,6]-苯基-C 71-丁酸甲酯(PC 71 BM)作为电子受体,所得聚合物太阳能电池表现出出色的光伏性能,功率转换效率为4.89 %,开路电压0.84 V,短路电流10.04 mA cm–2,填充率为56.0%。
