Abstract

Herein, we report the influence of solvent on the self-assembly of a dinuclear helicate, (NMe₄)₂[Eu₂(LR)₄]. A multiple species mixture with the chemical composition of [Eu₂(LR)_2n]^n- present in CH₃CN can be transformed into a helicate upon increasing the content of CHCl₃, accompanied by a significant enhancement in circularly polarized luminescence activity.
