Abstract
The influence of β-diketone forms on the luminescence intensity of lanthanide compounds in a series of ligands, acetylacetone (trifluoroacetylacetone, benzoylacetone)—their unsaturated analogues (monomeric form)—copolymers of the latter with styrene (methylmethacrylate), was studied. Lanthanides in compounds with copolymers have been established to demonstrate the brightest luminescence. It was found that its intensity depends not only on the character of the substituent (CH3, CF3, C6H5) in the β-diketone molecule, but also on the distance between the β-diketone fragments in the copolymer. Reasons explaining the high intensity of luminescence in lanthanide–copolymer compounds are considered.
