Abstract

Starting from Kryptofix 22 two different branches were covalently attached through the nitrogen atoms, one containing a fluorescent moiety and the other the stable free radical TEMPO. The novel derivative exhibits fluorescence and paramagnetic properties, while the diaza-crown part ensures the affinity for alkaline metal-ions.

摘要

从穴状配体22开始，通过氮原子共价连接了两个不同的分支，一个含有荧光部分，另一个含有稳定自由基TEMPO。这种新型衍生物具有荧光和顺磁性质，而二氮杂冠醚部分确保了对碱金属离子的亲和力。
