Аннотация:A novel type of nanocomposite material (NCM) based on a multifunctional org. compd. (dithiacrown-ether deriv. of a styryl dye) in the polymeric matrix of polyvinylchloride contg. a plasticizer was obtained and studied for the 1st time. The fluorescence max. for such NCM is shifted by 15 nm to the short wavelength range in the presence of Hg2+ cations, and by 19 nm in the presence of Ag+ cations. The absorption max. under similar conditions shifts by 26 and 25 nm, resp. Thus, such NCM are promising for the quant. and qual. detn. of these cations in solns. by optical methods.
