Dibenzo-24-crown-8 (DB24C8) and dibenzylammonium (DBA) are always utilized for the construction of supramolecular assemblies. We reported a new kind supramolecular assembly polymer constructed by M1 which was synthesized from tetraphenylethene (TPE) linked with DB24C8 and DBA through click reaction. The chemical structures of all the compounds were fully characterized by 1H NMR, 13C NMR, and MS. The 1H NMR titration showed that the supramolecular assembly was successfully constructed in acidic condition. The fluorescent results showed that the assemblies displayed ratio-metric properties with the changes of aggregation-induced emission and monomer-emission, and fluorescence quenching with addition of Pd2+.

Key words: tetraphenylethene, DB24C8, secondary ammonium ion, supramolecular polymer, aggregations-induced emission
