An actinide polyrotaxane compound URCP1 with characteristic green fluorescence from uranyl centers was prepared through the utilization of an end‐cutting pseudorotaxane precursor with only the cucurbit[6]uril (CB[6]) macrocyclic components acting as linking struts. The non‐coordinating guest motif in URCP1 has increased freedom and structural flexibility, and displays intriguing temperature‐triggered dynamic conformational variations inside the cavity of CB[6].
