A series of new-type of donor-pi-acceptor dyes (TCT-1-6) utilizing 1,3,5-triazine as pi spacers were synthesized. These dyes were characterized by H-1 NMR, ESI-MS, EA, and X-ray crystallography. Their photovoltaic performances were also investigated. An overall photon-to-electron conversion efficiency of 1.8% was achieved with the DSSC based on the dye TCT-1(J(sc) = 3.33 mA/cm(2), V-oc = 757 mV, FF = 71.8%) under AM 1.5G illumination (100 mW/cm(2)).
