主 题：metallofullerene nanohoop electron spin fluorescence host–guest interaction
摘 要：Spin-based interdisciplinary research has attracted considerable attention,and various applications in magnetic memory,quantum science,and precision measuring technology have been *** this study,we induced a fluorescence property in a spin-active molecule by supramolecular assembly and realized a synergistic modulation of its spin and fluorescence properties.A Saturn-shaped supramolecular complex was synthesized using a spin-active metallofullerene Sc_(3)C_(2)@C80 with a fluorescent nanohoop of tetra-benzothiadiazole-based[12]cycloparaphenylene(TB[12]CPP),and its spin and fluorescence properties were comprehensively ***-dependent electron paramagnetic resonance(EPR)spectroscopy and fluorescence analyses were *** changes in the EPR signals and fluorescence peaks were discovered in the temperature range of 170–290 *** on nuclear magnetic resonance observations and theoretical calculations,a temperature-dependent host–guest interaction between Sc_(3)C_(2)@C_(80)and a nanohoop was demonstrated,which explained the synchronous changes in the EPR signals and fluorescence peaks for Sc_(3)C_(2)@C_(80)⊂TB[12]*** application of Sc_(3)C_(2)@C_(80)as a molecular spin system to probe the host–guest interaction was also *** results show that the supramolecular assembly can be used to design advanced spin systems coupled with optical and magnetic behaviors based on paramagnetic and luminescent molecules.
