LANGMUIR AND LANGMUIR-BLODGETT-FILMS OF A PHOSPHORUS DERIVATIVE

We have studied the ability of a novel molecule (diphenyl bis(octadecy lamino) phosphonium bromide) to form both Langmuir films and Langmuir- Blodgett films under different experimental conditions. It has been fo und that this substance is capable of forming stable monolayers at the air-water interface and building up highly ordered LB films yielding Z-type LB films of high quality (transfer ratio of 1) which were chara cterized by UV-vis and IR spectra, electron microscopy, and X-ray diff raction.
