The present invention relates to compounds of general formula I
wherein R100 and R200 are each independently hydrogen, C1-C10-alkyl which in case of C2-alkyl may be interrupted by one and in case of C3-C10-alkyl by one or two nonadjacent oxygen atoms, C5-C7-cycloalkyl, aryl, aryl-C1-C10-alkyl or aryloxy-C1-C10-alkyl, D is an m-valent (m=1, 2 or 3) donor moiety which comprises at least one carbon-carbon or carbon-heteroatom double bond and/or at least one unfused or fused carbo- or heterocyclic ring, A is an acceptor moiety which comprises at least one carbon-carbon or carbon-heteroatom double bond and/or at least one unfused or fused carbo- or heterocyclic ring, and the donor moiety D and the acceptor moiety A are π-conjugated to one another.
Furthermore, the present invention relates to the use of compounds of formula I for producing dye-sensitized solar cells and to dye-sensitized solar cells comprising compounds of formula I.
本发明涉及一般式I的化合物,其中R100和R200各自独立地为氢、C1-C10烷基,其中在C2烷基的情况下可能被一个,而在C3-C10烷基的情况下可能被一个或两个不相邻的氧原子所打断,C5-C7环烷基,芳基,芳基-C1-C10烷基或芳氧基-C1-C10烷基,D是一个m价(m=1、2或3)供体基团,其中包括至少一个碳-碳或碳-杂原子双键和/或至少一个未融合或融合的碳或杂环状环,A是一个受体基团,其中包括至少一个碳-碳或碳-杂原子双键和/或至少一个未融合或融合的碳或杂环状环,供体基团D和受体基团A彼此π共轭。此外,本发明涉及使用式I的化合物制备染料敏化太阳能电池,并包括式I的化合物的染料敏化太阳能电池。
