Abstract Ultrafast dynamics and third-order nonlinearity of thin films of tert-butyl peripherally-substituted indium phthalocyanine axially grafted polystyrene (tBu4PcIn--PS) are investigated by femtosecond optical-Kerr-effect (OKE) and z-scan experiments. The fastest component (< 200 fs) in the OKE traces of the film is related to the electron cloud distortion, where the phthalocyanine-polymer interaction may enhance this contribution. The z-scan measurement also indicates that this interaction might enhance the third-order optical nonlinearity. The measurements shows that the magnitudes of X3 of these films are in order of 10-11esu.
