A highly reactive electrophilic bromodifluoromethylthiolating reagent, α-cumyl bromodifluoro-methanesulfenate 1, was prepared to allow for direct bromodifluoromethylthiolation of aryl boron reagents. This coupling reaction takes place under copper catalysis, and affords a large range of bromodifluoromethylthiolated arenes. These compounds are amenable to various transformations including halogen exchange
Six new heteroleptic Ru(II) complexes (MC118, MC120–123 and MC126), of general formula Ru(L1)(L2)(NCS)2, where L1 and L2 are respectively dicarboxylated and π-conjugated functionalized (dissymmetric) bipyridine ligands, were designed, synthesized and applied as sensitizers in dye-sensitizedsolarcells. These complexes were characterized both experimentally and theoretically, showing promising optical
六个新杂的Ru(II)络合物(MC118,MC120-123和MC126),通式的钌(L1)(L2)(NCS)2,其中L1和L2分别二羧基化和π共轭官能(不对称)联吡啶配位体被设计,合成并用作染料敏化太阳能电池中的敏化剂。这些配合物在实验和理论上都进行了表征,与典型的N719染料相比,显示出令人鼓舞的光学特性,具有更高的消光系数。当与液体Ⅰ工作装置,组合使用- / I 3 - 氧化还原电解质,研究过的敏化剂的功率转换效率在6.0%至8.0%之间,与在相似的制造和评估条件下测试的参比N719染料相当。
Ligand Engineering for the Efficient Dye-Sensitized Solar Cells with Ruthenium Sensitizers and Cobalt Electrolytes
because of the poor compatibility between the ruthenium(II) sensitizer and the cobalt redox species. To address this problem and achieve higher power conversion efficiencies (PCEs), we introduce here six new cyclometalated ruthenium(II)-based dyes developed through ligand engineering. We tested DSCs employing these ruthenium(II) complexes and achieved PCEs of up to 9.4% using cobalt(3+/2+)-based electrolytes
