Synthesis, photophysical and electrochemical properties of triazolyl dendrimers with thiazolylchalcone surface unit

Synthesis of novel triazolyl dendrimers with thiazolylchalcone surface group and triazole as bridging unit has been achieved in good yields by click chemistry via convergent approach. All the triazolyl dendrimers showed an absorption band between 293-336 nm and an emission band between 430-435 nm. The intensity of the absorption and emission bands increases on increasing the number of dendritic wedges and triazole units. Triazolyl dendrimers exhibited quasi reversible behaviour in cyclic voltammetry. A shift in the reversible potential was observed in cyclic voltammetry on increasing the dendritic wedges in the triazolyl dendrimers.
