For a complex equipped with carboxy anchoring groups, the performance in a dye-sensitized solar cell is evaluated. The title complexes are readily synthesized and can be decorated with alkyl chains utilizing azide-alkyne cycloaddition methods, in order to improve the device stability and allow the use of alternative electrolytes. On account of the strong electron donation from the 1,2,3-triazolates, the complexes exhibit a broad metal-to-ligand charge-transfer absorption (up to 700 nm), leading to an electron transfer toward the anchoring ligand. The lifetimes of the charge-separated excited states are in the range of 50 to 80 ns. In addition, the ground- and excited-state redox potentials are appropriate for the application in dye-sensitized solar cells, as demonstrated by power conversion efficiencies of up to 4.9\% (vs 6.1\% for N749).}, issn = {0020-1669}, doi = {10.1021/ic402701v}, author = {Sinn, Stephan and Schulze, Benjamin and Friebe, Christian and Brown, Douglas G. and Jaeger, Michael and Kuebel, Joachim and Dietzek, Benjamin and Berlinguette, Curtis P. and Schubert, Ulrich S.} }
