Popis: Four novel high-dimensional metal–organic rotaxane frameworks (MORFs) were successfully fabricated by cucurbit[6]uril-based pseudorotaxanes ([PR43]) and rigid carboxylate ligands by adjusting the synthesis temperature and the length of ligands. Compound 1 represents a three periodic 2-fold interpenetrating dia network based on a binuclear {Cd2Cl4O4} second building unit (SBU). 2 and 3 are isostructural pcu networks constructed by binuclear and trinuclear cadmium clusters, respectively, while compound 4 is a two-dimensional layered network with a large grid 44.3 × 19.8 A2. Furthermore, their fluorescent properties in different solvents are investigated.
