Abstract

The reaction of europium dibenzoylmethanate complex Na+[Eu(Dbm)4]– with 1-alkyl-4-dimethylaminopyridinium salts gives compounds [RNC5H4NMe2]+[Eu(Dbm)4]– (Dbm = [PhC(O)CHC(O)–Ph]), where R = C10H21 (I) or a set of oligomers CnH2n+1, (n is even) ([(R-NC5H4NMe2)]I) with a weight-average molecular weight Mw = 1520 (II). The molecular structure of complex I was established by X-ray diffraction analysis (CCDC no. 2405293). Compounds I and II were used as the luminescent components for a luminescent composite material based on low-density polyethylene (LDPE). The optical properties of complexes I and II and LDPE-based composite materials prepared using I and II were investigated.
