Published: Jan. 14, 2024

Abstract Smart luminescent materials that have the ability to reversibly adapt external environmental stimuli and possess a wide range of responses are continually emerging, which place higher demands on means regulation response sites. Here, europium ions (Eu 3+ )‐directed supramolecular metallogels constructed by orthogonal self‐assembly Eu based coordination interactions hydrogen bonding. A new organic ligand ( L ) is synthesized, consisting crown ethers two flexible amide bonds‐linked 1,10‐phenanthroline moieties coordinate with . Synergistic intermolecular bonding in ‐ enable self‐assemble into shape‐persistent 3D MeOH solution. The key success utilization ethers, playing dual roles acting both as building blocks build C 2 ‐symmetrical structure, ideal monomer for increasing energy transfer from ’s excited state, thus maintaining excellent luminescence metallogels. Interestingly, such assemblies show K + , pH, F − mechano‐induced reversible gel‐sol transitions tunable properties. Above findings useful studies molecular switches, dynamic assemblies, smart materials.
