SPECTRAL-LUMINESCENT PROPERTIES OF ALKOXYSILANE-METALLOPHTHALOCYANINE CONJUGATES COVALENTLY BONDED TO THE POLYMERIC CHAINS OF SILICATE GEL MATERIALS

Conjugates of metal hydroxyl phthalocyanines (М(ОН)_nРс; М = Si, Ge, Al, Ga) with 3-aminopropyltriethoxysilane (APTEOS) are synthesized. By means of the sol-gel method, polymeric silicate gel materials doped with the (APTEOS)_n-М(ОН)_nРс conjugates are prepared: the latter form structural links in the composition of the copolymer with the siloxane fragments of the polymeric chains (in the case of n=2) or are “grafted” to such chains in the form of side substituents (n = 1). It is shown by the spectral-luminescent methods and the methods of kinetic spectroscopy that the (APTEOS)_n-М(ОН)_nРс conjugates, on the introduction into a silicate gel material, retain their molecular structure and the photophysical characteristics of MPcs in the monomeric form. The obtained macromolecular substances are promising as monomeric dopants in new functional materials for optics and quantum electronics.
