A new photochromic complex of Keggin type molybdophosphoric acid/polycarbonate has been synthesized.Their properties were investigated by IR spectrum, UV spectrum and 31P NMR. The results of IR spectra and UV spectra indicate that thereis interaction between the H3PMo12O40 and polycarbonate.The complex has photosensitivity under irradiation of sunlight to result from the interation between the C=O of PC and the H of the molybdophsphoric acid.
