Molecular thin films of porphyrin dimers prepared by the Langmuir–Blodgett (LB) technique
Abstract
Molecular thin films of the porphyrin derivative ruthenium mesoporphyrin-9-dimethyl ester carbonyl have been prepared on a range of substrates including hydrophobic glass, polyethylene, and silver bromide by the Langmuir–Blodgett (LB) technique; irradiation of the films yields dimers, containing RuRu bonds, which have been characterised by u.v. and i.r. spectroscopy.
