Abstract: | Benzo-21-crown-7(B21 C7) is one of the most important crown ethers,which not only shows excellent physicochemical properties but also exhibits promising binding capability with dialkylammonium salts.In this paper,we designed and synthesized a fixed-tetraphenylethylene(FTPE) motif bridged ditopic benzo-21-crown-7 molecule(H).The fixed tetraphenylethylene motif endows H with aggregation induced emission(AIE) prope rty.In the presence of a ditopic dialkylammonium salt guest molecule(G),a fluorescent supramolecular polymer with golden luminescent property could be fabricated.This B21 C7-based host-guest supramolecular polymer with golden fluorescence may have potential application in dynamic luminescent materials. |
