Abstract
The photopolymerization of linoleic acid monolayers on a TbCl3 subphas e at various pH values has been studied by UV-VIS spectroscopy and mea surements of the kinetic changes of the mean molecular area. Dramatic differencies in the topography of the linoleic acid Langmuir-Blodgett (LB) film structures at various pH values were observed by atomic forc e microscopy. UV-VIS spectroscopic measurements indicated the formatio n of a charge-transfer complex between adjacent acid molecules. The ex perimental results for the best reaction conditions were fitted by a f irst-order kinetic model which accounts for the two-dimensionality of the system.
