Description
Summary:Conjugates of metal hydroxyl phthalocyanines (M[(OH).sub.n]Pc; M = 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).sub.n]-M[(OH).sub.n]Pc 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 spectral-luminescent and kinetic spectroscopy methods that the [(APTEOS).sub.n]-M[(OH).sub.n]Pc conjugates, on the introduction into a silicate gel material, retain their molecular structure and the photophysical characteristics of MPc in the monomeric form. The obtained macromolecular substances are promising as monomeric dopants in new functional materials for optics and quantum electronics.
