主 题：valence tautomerization charge transfer photo switching diradical coordination polymer
摘 要：Organic radicals are widely used as linkers or ligands to synthesize molecular magnetic ***,studies regarding the molecular anisotropies of radical-based magnetic materials and their multifunctionalities are ***,a photoisomerizable diarylethene ligand was used to form{[CoⅢ(3,5-DTSQ·-)(3,5-DTCat2-)]2（6F-DAE-py2）}·3CH3CN·H2O(o-1·3CH3CN·H2O,6F-DAE-py2=1,2-bis(2-methyl-5-（4-pyridyl）-3-thienyl)perfluorocyclopentene),a valence-tautomeric（VT） coordination *** directly observed dual radicals for a single crystal using high-field/-frequency（～13.3 T and～360 GHz） electron paramagnetic resonance（EPR） spectroscopy along the c-axis,which was further confirmed by angle-dependent Q-band EPR ***,a conductive anomaly close to the VT transition temperature was observed only when probes were attached at the ab plane of the single crystal,indicative of synergy between valence tautomerism and *** anisotropy studies and density functional theory（DFT） calculations revealed that this synergy is due to electron transfer associated with valence *** study presents the first example of dual-radical-based molecular anisotropy and charge-transfer-induced conductive anisotropy in a photoswitchable coordination polymer.
