Abstract
Biradical 2,2':6',2''-terpyridine-6,6''-diyl bis(tert-butyl nitroxide) (tpybNO) showed intramolecular ferromagnetic coupling with 2J/kB = +2.14(10) K and its complex Zn(tpybNO)(MeOH)22 exhibited intramolecular antiferromagnetic coupling with 2J/kB = -7.5(4) K, suggesting exchange coupling switchable by means of supramolecular chemistry.
摘要
双自由基 2,2':6',2''-三联吡啶-6,6''-二基双(叔丁基氮氧自由基)（tpybNO）表现出分子内铁磁耦合，2J/kB = +2.14(10) K，其配合物 Zn(tpybNO)(MeOH)22 表现出分子内反铁磁耦合，2J/kB = -7.5(4) K，表明可以通过超分子化学进行交换耦合的开关。
