The present invention relates to a binuclear ruthenium complex dye having a substituted bipyridyl group and represented by the general formula (1):
wherein
R1, R2, R3 and R4 each independently represents a linear or branched alkyl group having 1 to 30 carbon atoms, with the proviso that at least one of R1 and R2 represents a linear or branched alkyl group having 10 to 30 carbon atoms and at least one of R3 and R4 represents a linear or branched alkyl group having 10 to 30 carbon atoms; X represents a counter ion;
n represents a number of the counter ions needed to neutralize a charge of the complex; and
proton(s) (H+) of one or more carboxyl groups (-COOH) may dissociate.
本发明涉及一种具有取代双
吡啶基团的双核
钌配合物
染料,其由通式(1)表示:其中R1、R2、R3和R4分别独立表示具有1至30个
碳原子的直链或支链烷基基团,但至少其中之一的R1和R2表示具有10至30个
碳原子的直链或支链烷基基团,至少其中之一的R3和R4表示具有10至30个
碳原子的直链或支链烷基基团;X表示一个反离子;n表示中和该配合物电荷所需的反离子数量;一个或多个羧基(-COOH)的质子(H+)可能解离。
