摘　　要：A series of SalenZn based dyes with triphenylamine derivatives as the donor,benzoic acid as the acceptor,and coplanar Salen complexes as the spacer have been designed and synthesized for dye-sensitized solar cells.The ab-sorption,electrochemical,and photovoltaic properties for all sensitizers have been systematically investigated.When the tail length of the alkyl substituents is increased from C-0 to C-8 on the donor part,the efficiency of its DSSC augments evidently.It is found that the incorporation of bis-carboxyl groups instead of the single carboxyl group as anchoring groups induces a remarkable enhancement of the electron injection efficiency from the excited dyes to the TiO_(2)semiconductor and generates higher electron density and voltage.
