Crystal Structure, and Luminescent Property of the Zinc(II) Complex Based on 2-Hydroxynaphthaldehyde

A new trinuclear Zn(II) complex [(ZnL)2(OAc)2Zn]·2THF with a Salamo-type bisoxime ligand H2L (2,2′-[ethylenedioxybis(nitrilomethylidyne)]dinaphthol) is synthesized and structurally characterized. The luminescence study demonstrates that the Salamo-type ligand exhibits a good antennae effect with respect to the Zn(II) ion due to an efficient intersystem crossing and ligand-to-metal energy transfer. From a more general perspective, this work opens interesting perspectives for the development of efficient luminescent stains to obtain a novel luminescent Zn(II) complex with Salamo-type derivatives.
