用顺式封闭的炔基铂金属配体(铂-L)和稀土(Ln=LaIII，EuIII，LuIII)离子构筑了一系列5d/4f强发光的5d/4f异金属有机大环，分子式为LN_2(铂-L)_2。多金属-有机大环上稀土中心的开放金属中心不仅有利于组装后修饰导致发光的极大增强，而且还有利于对有毒的硫代膦酸盐的位移传感。
A series of strongly luminescent 5d/4f heterometal–organic macrocycles formulated as Ln2(Pt–L)2 have been constructed from a preformed cis-blocked alkynylplatinum metalloligand (Pt–L) and lanthanide (Ln = LaIII, EuIII, LuIII) ions. Open metal sites on the lanthanide centres of the heterometal–organic macrocycles facilitate not only the post-assembly modification leading to great enhancement of the luminescence, but also the displacement sensing toward toxic thiophosphonates.
