摘要:
Dispersion characteristics of the monomolecular films of hematoporphyrin mixed with stearic acid has been studied. The average molecular areas of mixed monolayers coincided approximately with the ideal additivity rule when the“solid” films were extrapolated to zero surface pressure. The orientation of the macrocycles was given by infrared dichroism with the tilting angle of 10. 1° to the plane of the film. The SERS of LB films deposited on silver island films was observed- The results showed that there are two possible contribution, i. e., electromagnetic and chemical interaction between the hematoporphyrin molecules and Ag island films.
