Searching for new chemically durable and radiation-resistant absorbent materials for actinides and their fission products generated in the nuclear fuel cycle remain highly desirable, for both waste management and contamination remediation. Here we present a rare case of 3 D uranyl organic framework material built through polycatenating of three sets of graphene-like layers, which exhibits significant umbellate distortions in the uranyl equatorial planes studied thoroughly by linear transit calculations. This unique structural arrangement leads to high β and γ radiation-resistance and chemical stability in aqueous solutions within a wide p H range from 3 to 12. Being equipped with the highest surface area among all actinide compounds known to date and completely exchangeable [(CH)NH] cations in the structure, this material is able to selectively remove cesium from aqueous solutions while retaining the polycatenated framework structure.

Over the past two decades,significant effort has been focused on the crystal chemistry of actinide elements which is heavily dominated by the linear(UO)2+——uranyl ion with an emphasis on its critical role in the traditional nuclear fuel *** comparison,thorium is relatively less explored,mostly probably due to two reasons:first,thorium is not relevant to uranium based nuclear fuel cycle;second,the
