The high selectivity and reversibility of metal coordination enable precise modulation the structural morphology supramolecular assemblies, which is essential for development intelligent application functionalized materials. In this study, sheet-like assemblies (Pyr-O@tQ[14]) constructed by twisted cucurbit[14]urils (tQ[14]) pyrene derivatives (Pyr-O) through host-guest interactions, exhibit excellent optical properties, achieves highly sensitive detection Hg2+ fluorescence quenching, with a limit 0.177 μM. A novel smart platform, compatible smartphones, developed to enhance efficiency practicality practical applications. From microscopic perspective, adjusting concentration can change Pyr-O@tQ[14] from lamellar square finally spherical, demonstrating dynamic control assembly structure in response environmental stimuli. This study not only presents efficient quantitative sensing platform but also highlights unique advantages tQ[14] constructing tunable, responsive structures, opening new avenues design synthesis advanced
