The first enantiomerically pure 2,2′-bipyridine-based cryptand is reported. Complexation of this macrobicyclic ligand with the trivalent lanthanoidcations Yb and Lu produces enantiomerically and diastereomerically pure cryptates in solution. The Yb cryptate shows near-IR photoluminescence with lifetimes of up to τ = 29.8 μs in CD3OD.
报道了一种首个手性纯的2,2′-联吡啶基加密剂。该大环双环配体与三价镧系阳离子Yb和Lu的复合在溶液中产生了手性和非对映异构体纯的加密体。Yb加密体在CD3OD中表现出近红外光致发光,寿命可达τ = 29.8 μs。
