•The covalently linked POM/zinc(II) porphyrin hybrid was synthesized and characterized.•There is a strong delocalisation and charge transfer between POM and the grafted zinc porphyrin segments in the hybrid.•The hybrid displayed interesting electrical conductivity behavior and photovoltage response.
A novel covalently-linked organic-polyoxometalate (POM) hybrid compound [NBu4]6[α2-P2W17O61{P(O)Porp}2] (DM) (Porp = Zn(II)-5-(4-phenyl),10,15,20-triphenylporphyrin) was prepared by treating Dawson-type K10[α2-P2W17O61] (D) with Zn(II)-5-[4-(dihydroxyphosphoryl)phenyl],10,15,20-triphenylporphyrin (M), and characterized by NMR, IR, UV–vis, fluorescence spectra and cyclic voltammetry. The study on photophysical properties displayed that there is a strong delocalisation and charge transfer between D and the grafted zinc porphyrin segments in the hybrid compound DM. The redox potential of the polyanion can be tuned by the grafting zinc porphyrin segments on it. The DM displayed interesting electrical conductivity behavior and photovoltage response.
