D-pi-A fluorescentdye with two pyridyl groups as an electron-withdrawing-injecting anchoringgroup possessing a high coordinate bonding ability to Lewis acid sites on the TiO2 surface, which can lead to high dye loading on the TiO2 film and efficient electron injection, has been developed as a new type of D-pi-A dye sensitizer for dye-sensitizedsolarcells.
