摘要：
A new heteroleptic complex, [Ru(dcbH(2))(bpy)(9AA)Cl](2+), Ru-9AA (9AA = 9-aminoacridine), was synthesized, characterized and used along with the previously synthesized [Ru(dcbH(2))(bpy)(TCNE) Cl], Ru-TCNE (TCNE = tetracyanoethylene), in dye-sensitized solar cells (DSCs). The photoelectrochemical data were evaluated in comparison to the standard [Ru(dcbH(2))(2)(NCS)(2)] dye, N3. DSCs sensitized by these compounds exhibit overall efficiency conversion of 0.95 and 2.82% for Ru-9AA and Ru-TCNE, respectively, while that for N3 is 5.65% in the same condition. In spite of presenting lower global efficiencies than the standard dye, the Ru-TCNE complex present adequate electron injection efficiency and convert light into electricity effectively.
