The magnetic and magneto-optical properties of a tetrazinyl radical-bridged Er metallocene, [(CpEr)(bpytz)][BPh] (; Cp = pentamethylcyclopentadienyl, bpytz = 3,6-bis(3,5-dimethyl-pyrazolyl)-1,2,4,5-tetrazine), are reported. As confirmed by these studies strong Ln-rad coupling is achieved, with exhibiting slow magnetic relaxation under a 1000 Oe dc field. The optical and magneto-optical profile of is completed by both near-infrared (NIR) luminescence and magnetic circularly polarized luminescence (MCPL), representing the first example of NIR MCPL with Er.
报道了一种四嗪基自由基桥联铒金属茂[(CpEr)(bpytz)][BPh]（；Cp = 五甲基环戊二烯基，bpytz = 3,6 - 双(3,5 - 二甲基 - 吡唑基)-1,2,4,5 - 四嗪）的磁性和磁光性质。这些研究证实实现了强的镧系元素 - 自由基耦合，在1000奥斯特直流磁场下表现出缓慢的磁弛豫。通过近红外（NIR）发光和磁圆偏振发光（MCPL）完成了其光学和磁光特性描述，这代表了铒的近红外MCPL的首个实例。
