Abstract
The luminescent-spectral properties of molecules of 2,3,9,10,16,17,23,24-octacarboxyphthalocyanine and its zinc complex embedded in nanoporous silicate gel matrices were studied. It was found that H-aggregates of the phthalocyanines are formed at the initial stage of formation of the silicate framework. It was discovered that the monomeric form of the zinc complex in the gel matrix is restored when the silicate material is dried. The reasons for destruction of the aggregates in the restricted volume of the matrix of nanoscale pores are discussed. [ABSTRACT FROM AUTHOR]
