Luminescent properties of poly(alkyl methacrylate) polymer films modified with strongly polar phthalocyanine

Relaxation phenomena in latex polymer materials modified by ionic phthalocyanine

“…Owing to the physico chemical properties of phth alocyanines, such compositions can find application in optoelectronic industry (luminescent and photo sensitive systems corresponding to telecommunica tion wavelengths of fiberoptic communication lines) for development of new functionalized surface layers and films, ordered polymer nanocomposites based on nanostructured metal-oxide templates, etc. [5][6][7][8][9][10][11].…”

“…Earlier, we established the possibility of modifica tion of latex polymers based on emulsifier free film forming styrene alkyl(meth)acrylate latexes by water soluble 2,3,9,10,16,17,23,24 octa[(3,5 biscarboxy) phenoxy]phthalocyanine С 88 Н 42 N 8 Na 8 O 24 (WSP) owing to their full compatibility, as well as the stability of the latter in the presence of WSPs [12][13][14], which is a prerequisite for development of new composite materials with a set of practically important proper ties, particularly photochemical ones [5][6][7][8][9][10][11].…”

Relaxation inhomogeneity of the structure of latex polymers modified with water-soluble phthalocyanine

“…Earlier, in [5][6][7], the possibility to modify polymer films based on carboxyl containing styrene-alkyl methacrylate latexes with water soluble 2, 3,9,10,16,17,23,24 octa[(3,5 biscarboxy) phenoxy] phthalocyanine (WDP) was demonstrated. Full com patibility of a polymer and WDP, as well as stability of a latex with respect to WDP, makes it possible to develop a new composite material with a complex of practically important properties, in particular, photo chemical properties [7][8][9][10].…”

“…It was expected that the physicochemical proper ties of a polymer may vary during the preparation of a composition owing to the introduction of an ionic modifier that is capable of interacting with carboxyl groups of the polymer [5][6][7]. Dynamic mechanical relaxation spectroscopy was applied to clarify this question; this method is based on the analysis of the response of separate structural-kinetic elements of polymer systems to an external effect that disturbs them or the whole system from the state of mechanical and thermodynamic equilibrium [11].…”
