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.
