Three novel triphenylamine-based D-A-r-A-featured dyes （Zl-Z3） have been designed, synthesized and characterized for use in dye-sensitized solar cells. Benzothiazole was incorporated as an additional acceptor, which greatly enhanced the molar ex- tinction coefficient of the dyes. Various conjugated linkers, such as benzene, furan and thiophene, were also introduced to con- figure the novel D-A-n-A framework in order to prolong electron flow and active transportation. Among all dyes, Z2 contain- ing a thiophene linker exhibited the maximum overall conversion efficiency （r/） of 4.16% （Jsc = 9.27 mA cm-2, Voc = 642 mV, FF = 0.70） under standard global AM 1.5 G solar condition.
