Description

Research objects - lanthanide complexes based on aminopolycarboxylic acids and calix[4]arenes, modified with silicon-containing substituents and hybrid organic-inorganic materials based on them. Research goal - development of techniques for covalent immobilization of modified acyclic and cyclic compounds to produce hybrid and polymeric materials, studying of their structural and photophysical characteristics to establish the influence of the matrix on the efficiency of 4f-luminescence. Luminescent organic-inorganic hybrid materials containing immobilized complexes of lanthanides (III) modified with ethylenediamine- and diethylenetriamine- pentaacetic acids and p-tert-butylcalix[4]arene was prepared by means of a sol-gel method. It was revealed that obtained composites exhibit fluorescence in the visible region and 4f-luminescence in the visible and near-infrared range. Covalent binding of the complexes in matrix allow to considered obtained materials as promising for creating photo and chemically stable fluorescent sensors and optical devices.
