摘要

A radical change: Two 3D Zn~(II) complexes with pillared structures have been synthesized from a triamine-based polycarboxylate ligand under hydrothermal conditions. The complexes exhibit reversible radical-based redox photochromism that varies from yellow to bluish-violet and dark blue, respectively, under UV/blue irradiation, and fluorescence with adjustable intensity. The ESR and X-ray photoelectron spectroscopy studies verify photochromic mechanisms based on electron transfer.
