Porphyrin–polyoxometalate hybrids connected via a Tris-alkoxo linker for the generation of photocurrent

Abstract Films on ITO of [N(C 4 H 9 ) 4 ] 5 H[P 2 V 3 W 15 O 59 {(OCH 2 ) 3 CNHCO(ZnTPP)}] (ZnTPP = zinc(II)-tetraphenylporphyrin) were obtained by the Langmuir–Schaefer inverted transfer method. The films were characterized by UV–vis absorption spectroscopy, XPS, AFM, and electrochemistry. In addition, the photovoltaic performances of the Langmuir–Schaefer films were investigated by photocurrent transient measurements, which show significant photocurrent response.
