摘要：

The photovoltaic stability of Ru-II(LH2)(2)(NCS)(2) (where LH2 = 2,2'-bipyridyl-4,4'-dicarboxylic acid), a potential sensitizer for solar cells based on anatase, is examined. Its suitability for this role is demonstrated by a 7000 h endurance test, at the end of which no discernible signs of degradation can be detected. An explanation for its remarkable stability is provided by an investigation of its photo-and thermally induced reactions in alcoholic solution. Recommendations as to how to avoid ligand substitution reactions that may be undesirable for certain applications are also made.
