Anthocyandin is a natural pigment which can be used as a dye in Dye-Sensitized Solar Cells (DSSC). DSSC devices generate electricity by transferring electrons from an excited dye molecule to titanium dioxide in an electrolyte medium. Along with other key functions of the cell device, the absorption of light energy by dye molecules is also a crucial role. In order to improve efficiency of light harvesting in the device, a series of artificial anthocyanidins with various functional groups including a phenyl ring, amine, and nitro group on the flavylium ring were synthesized. Their photochemical properties depending on their functional groups were studied using UV-Vis spectroscopy.<br/>The products were confirmed and characterized by UV/Vis, IR and NMR spectroscopies.
