The concept of “robust dynamics” describes the incorporation of mechanically interlocked molecules (MIMs) into metal-organic framework (MOF) materials such that large amplitude motions (e.g., rotation or translation of a macrocycle) can occur inside the free volume pore of the MOF. To aid in the preparation of such materials, reticular synthesis was used herein to design rigid molecular building blocks with predetermined ordered structures starting from the well-known MOF NOTT-101. New linkers were synthesized that have a T-shape, based on a triphenylene tetra-carboxylate strut, and their incorporation into Cu(II)-based MOFs was investigated. The single-crystal structures of three new MOFs, UWCM-12 (fof), β-UWCM-13 (loz), UWCM-14 (lil), with naked T-shaped linkers were determined; β-UWCM-13 is the first reported example of the loz topology. A fourth MOF, UWDM-14 (lil) is analogous to UWCM-14 (lil) but contains a [2]rotaxane linker. Variable-temperature, ²H solid-state NMR was used to probe the dynamics of a 24-membered macrocycle threaded onto the MOF skeleton.

“健壮的动力学”的概念描述了将机械互锁的分子（MIM）结合到金属有机骨架（MOF）材料中，使得大振幅运动（例如，大环的旋转或平移）可能发生在分子的自由体积孔内。 MOF。为了帮助制备这种材料，本文使用网状合成来设计具有预定的有序结构的刚性分子构件，该结构从众所周知的MOF NOTT-101开始。基于三亚苯基四羧酸酯撑杆，合成了具有T形的新接头，并研究了它们如何结合到基于Cu（II）的MOF中。UWCM-12（fof），β- UWCM-13（loz），UWCM-14三个新MOF的单晶结构（lil），确定具有裸露的T形接头；β- UWCM-13是首次报道的loz拓扑示例。第四MOF，UWDM-14（LIL）类似于UWCM-14（LIL），但含有[2]轮烷接头。使用温度可变的² H固态NMR来探测连接到MOF骨架上的24元大环的动力学。
