Abstract

A dinuclear europium(III) complex with a structure of [BP-(Eu^III)₂-(ODA)₃] (BP = 2,2′-bipyridine-6,6′-dicarboxylic acid bis(N-hydroxy-succinimide) ester, ODA = diglycolic acid) shows a fully reversible emission spectral change at the extremely narrow ⁵D₀ → ⁷F₂ transition band in response to temperature changes ranging from 283 K to 333 K.
