Abstract: | Synthesis of novel dendrimers with benzothiazole as surface group and triazole as branching unit is achieved through click chemistry. The presence of more number of benzothiazole and triazole units increases the molar absorption coefficient and alters the fluorescence as well as electrochemical behaviors in the dendrimers. Dye-sensitized solar cell (DSSC) studies reveal that dendrimers with more number of benzothiazole and triazole groups exhibit better current generating capacity than the dendrimers with lesser number of benzothiazole and triazole groups. Dendrimer 2b shows the maximum current conversion efficiency (η) of 7.1%. |
