Electrochemical anodic synthesis of Tb3+ luminescent coordination compounds with some fluorophenylacetic acids

the results of electrochemical anodic synthesis of coordination compounds of terbium(III) with pentafluorophenylacetic and 2,3,5,6tetrafluoro-4(trifluoromethyl)phenylacetic acids are reported. The structure and properties of terbium(III) synthesized coordination compounds were held by the IRand luminescence spectroscopy. According to IR-spectra data, the bond type of carboxylated ligand’s atom with lanthanid’s ion is mainly ionic. It was found out that at the room temperature terbium (III) complex compounds luminesce in visible area (green luminescence) and have emission bands, corresponding to Tb3 ion energy transitions.
