Solvent Modification of the Structures and Magnetic Properties of a Series of Dysprosium(III) Single-Molecule Magnets. Hong-Qing Li, Guo-Lu Wang, Yu-Chen Sun, Yi-Quan Zhang, Xin-Yi Wang.This article is cited by 220 publications. This work realized the radicals-actuated on/off SMM behavior via RT light irradiation, providing a new strategy for constructing the light-induced SMMs. For the first time, we observed the reversible RT photochromism and photomagnetism in the lanthanide-based materials. radicals, showing SMM behavior after RT illumination.Strong ferromagnetic coupling with remarkably slow magnetic relaxation without applied dc fields was observed between Dy III ions and photogenerated O More importantly, the PET process induced significant variations in magnetic interactions for the Dy(III) congener. All the compounds exhibited reversible photochromic and photomagnetic behaviors via UV light irradiation at RT, induced by the photogenerated radicals via a photoinduced electron transfer (PET) mechanism. H 4–HEDP♱0H 2O ( QDU-1 Ln = Dy ( QDU-1(Dy)), Gd ( QDU-1(Gd)), and Y ( QDU-1(Y)) HEDP = hydroxyethylidene diphosphonate TPT = 2,4,6-tri(4-pyridyl)-1,3,5-triazine) were synthesized by solvothermal reactions.Herein, a series of chain complexes ♲H 3–TPT
Exploitation of room temperature (RT) photochromism and photomagnetism to induce single-molecule magnet (SMM) behavior has potential applications toward optical switches and magnetic memories, and remains a tremendous challenge in the development of new bulk magnets.
