Functionalized alkyne bridged dendron based chromophores for dye-sensitized solar cell applications

Abstract

We report the results of an investigation on the preparation, spectral and photoelectrochemical properties of alkyne bridged dendron chromophores with carboxylic acid anchoring group, which adhere effectively to nanocrystalline (anatase) TiO2 surfaces yielding incident photon-to-current conversion efficiency values of up to 76% in their photocurrent action spectra, suggesting that the alkyne π-bridge functional moiety is an effective bridging group between chromophore and conduction band of the semiconductor.
