Films on ITO of IN(C4H9)(4)](5)H[P2V3W15O59{(OCH2)(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.
