POLYMER LIGAND WITH ANTHRANILAMIDE MAIN-CHAIN UNITS AND METAL POLYMER COMPLEX CONTAINING SUCH LIGAND Russian patent published in 2009 - IPC C08G73/00 C08G73/10 C09K11/06 

FIELD: chemistry.

SUBSTANCE: invention refers to polymer ligand with athranilamide main-chain units and to metal polymer complex wherein polymer ligand forms luminescent complexes with rare earth ions. Polymer ligand is described with the general formula -(A-B)_m-: where A is a fragment of methylene-bis-anthranilic acid, B is a fragment of dicarboxylic acid chosen from dicarboxylic acid series, R= -(CH₂)₆-, -(CH₂)₇-, -(CH₂)₈-, m refers to values MM within 80 kDa to 200 kDa. Metal polymer complex based on polymer ligand is described with the general formula -(A-B)_m-Me: , where A is a fragment of methylene-bis-anthranilic acid, B is a fragment of dicarboxylic acid chosen from dicarboxylic acid series,

, m refers to values MM within 80 kDa to 200 kDa, Me is rare-earth metal from the group including Tb³⁺ and Eu³⁺, in ratio metal ion: metal polymer complex, wt % 0.3-3.9.

EFFECT: invention allows for high-strength metal polymer complex of improved thermal stability and luminescence intensity.
