Preparation and Properties of Nanofilms Based on Polymethine Dyes by Langmuir-Blodgett Technology

摘要

A study of physico-chemical properties of monomolecular layers of amphiphilic cationic polymethineuddye - thiacarbocyanine on the surface of the water subphase and the conditions of obtaining of Langmuir-udBlodgett (LB) films are presented. The value of area, occupied by one molecule of the dye in different statesudof monolayer was defined. The spectral-luminescent properties of cationic polymethine dye was studied. Anudexcimer fluorescence in LB films was revealed. It was shown, that in LB films, unlike solutions excimer notudforms from monomers, but it forms from dimers of dyes. A possible mechanism of their formation was considered.When you are citing the document, use the following link http://essuir.sumdu.edu.ua/handle/123456789/35155
