THE INFLUENCE OF ANION NATURE OF ALKALINE METAL SALT ON SPECTRAL-LUMINESCENT PROPERTIES OF F-S-HETERONUCLEAR COMPLEXES ON THE BASE OF CROWN-PORPHYRINS
Abstract
The heteronuclear complexes on the base of meso-tetra-crown-ether substituted porphyrins of «sandwich»-type which two ytterbium ions coordinated with porphyrin macrocycles, and four cations of alkaline metals (Na, K, Cs) situated between the cavities of benzo-12-crown-4-, benzo-15-crown-5- and benzo-18-crown-6-ethers, respectively, were obtained. The influence of anion nature of salts (bromide, nitrate, thiocyanate) on 4f-luminescence of Yb8+ ions in these complexes were analyzed.
