Spectral, luminescent, and lasing characteristics of pyridyloxazole derivatives in inorganic and hybrid gel materials
Tóm tắt
The spectral, luminescent, lasing, and photochemical characteristics of two pyridyloxazole derivatives incorporated during the sol-gel synthesis into inorganic silicate and hybrid organic-inorganic xerogels in the form of bulk matrices and thin films are studied. It is found that organic molecules are fixed in nanopores of solid matrices by specific interactions between proton-accepting centers of molecules and proton-donating centers of silicate matrices and create cationic and dicationic forms under such interactions. It is shown that pyridyloxazoles are more photostable in solid xerogels than in solutions.
