Abstract
Abstract The complexes piperidinium tetrakis(1,3-diphenyl-1,3-propanediono)europium(III) 3-hydrate and tetrapropylammonium tetrakis (4,4,4-trifluoro-1-(2-thienyl)-1,3-butanediono)europium(III) have been prepared. In these compounds, the europium is octa-coordinated. The performance of the complexes as pigments for polystyrene has been investigated; weather resistance, light fastness, migration resistance and heat stability have been considered.
