The optical and non-linear optical proper-ties of peripheral-substituted vanadium oxide phthalocyanine (VOPc) film and substituted VOPc/polymer composite film were investigated using stationary and transient spectroscopy techniques. The absorption Q band of the VOPc/polymer composite film shows a red shift relative to that of the peripheral-substituted VOPc film, revealing the monomeric characteristics of VOPc molecules. Effective quenching of PL emission was observed for the VOPc/polymer composite film and could be assigned to the efficient VOPc-polymer interaction. From pump-probe and optical Kerr effect (OKE) measurements, two decay components were obtained by fitting the transients for both VOPc films. The fast component., in a femtosecond time domain, originates from the electron-phonon interaction, and the difference in their slow decay is an indication of an efficient ISC process in the VOPc/polymer composite film, The third-order non-linear optical susceptibilities of these films were determined to be in the order of 10(-11) esu.
