| titleOfInvention | Radiation-protective lanthanide-containing compounds |
| abstract | FIELD: chemistry. n SUBSTANCE: invention relates to lanthanide-containing compounds, consisting of a copolymer of ethyl methacrylate and 3-allylpentanedione-2,4 (100:1), bonded through a β-diketonate group with a lanthanide (+3) ion, which in turn is bonded with molecules of a ligand which is β-diketone of general formula: , where Ln is a lanthanide (+3) ion (La 3+ , Pr 3+ , Nd 3+ , Sm 3+ , Eu 3+ , Gd 3+ Tb 3+ , Dy 3+ , Ho 3+ , Er 3+ , Tm 3+ , Yb 3+ ), n is the number of ethyl methacrylate links in the copolymer chain; m is the number of lanthanide-containing links in the copolymer chain; R 1 , R 2 , R 3 , R 4 are organic radicals (CH 3 - methyl, C 6 H 5 -phenyl): - R 1 =R 2 =R 3 =R 4 =CH 3 - lanthanide (+3) ion, bonded with the polymer part of the compound through a pentanedione-2,4 fragment (acetyl acetone) and a ligand which is acetyl acetone; - R 1 = R 3 = CH 3 , R 2 =R 4 =C 6 H 5 - lanthanide (+3) ion bonded with the polymer part of the compound through benzoyl acetone fragment and a ligand which is benzyol acetone; - R 1 =R 2 =R 3 =R 4 =C 6 H 5 - lanthanide (+3) ion bonded with the polymer part of the compound through a dibenzoyl methane fragment and a ligand which is dibenzoyl methane; - R 1 =R 3 =R 4 =CH 3 , R 2 =C 6 H 5 - lanthanide (+3) ion bonded with the polymer part of the compound through a benzoyl acetone fragment and a ligand which is acetyl acetone; - R 1 =R 2 =C 6 H 5 , R 3 =R 4 =CH 3 - lanthanide (+3) ion bonded with the polymer part of the compound through a dibenzoyl methane fragment and a ligand which is acetyl acetone; - R 1 =R 2 =R 3 =C 6 H 5 , R 4 =CH 3 - lanthanide (+3) bonded with the polymer part of the compound through a dibenzoyl methane fragment and a ligand which is benzoyl acetone. Said compounds have radiation-protective properties. n EFFECT: obtaining material which is optically transparent in the visible and ultraviolet range and resistant to ionising radiation. n 1 ex, 1 tbl, 9 dwg |
