摘要：
The LB films of two metalloporphyrin complexes with different substituents (NiTPP(OH), CuIITPP(COOH)) have been investigated. The pi - A isotherms are given. The composition and structure of the films were identified by XPS, UV-visible spectra, SEM, polarized absorption and X-ray diffraction. Interaction between molecules in the films of NiTPP(OH) was evident from the red shift in the visible spectroscopy, while that of CuIITPP (COOH) was not. The porphyrin ring of the NiTPP (OH) molecule was tilted on the subphase surface and transferred onto substrates in a similar orientation, but that of CuIITPP(COOH) was parallel to the film plane. The electric resistance of NiTPP(OH) films was less than that of CuIITPP(COOH) by ten orders of magnitude.
