Studies on Preparation of Composite Films by Adsorption of Methyl Orange Molecules onto the Interface of Tetracationic Porphyrazine Monolayer

摘要

The composite monolayer and Langmuir-Blodgett(LB) films of cobalt tetrahexadecyl tetrapyridino porphyraziniumbromide (TA16PyPzCo)/methyl orange (MO) were characterizedby surface pressure-area (#pi#-A) isotherm, UV-VIS spectra,polarized UV-VIS spectra, TEM and SAXD. The MO moleculeswere arranged with a special orientation in the composite films.The composite films have an ordered lamellar structure.
