Synthesis, photophysical and electrochemical properties and DSSC application of triphenylaminochalcone cored dendrimers with anthracene and pyrene as surface groups and triazolylcholanoate as the bridging unit

Abstract

Triphenylaminochalcone-cored dendrimers decorated with anthracene and pyrene at the periphery have been synthesized by a convergent methodology using a click chemistry approach and characterized from spectral data and elemental analyses. All the dendrimers show excellent optical and electrochemical properties. Higher generation dendrimers exhibit better power conversion efficiency than lower-generation dendrimers when used as additives in dye-sensitized solar cells (DSSCs).
