Construction of two-dimensional supramolecular nanostructure with aggregation-induced emission effect via host-guest interactions
A tetraphenylethene (TPE) based water-soluble molecule was synthesized. Two-dimensional supramolecular nanostructure with obvious aggregation-induced emission effect was constructed through the host-guest interactions between the TPE derivative and CB. The assembly proccess and the 2D structure were confirmed by the 1H-NMR, SEM, TEM and SAXS. A high affinity for DNA and obvious fluorescence enhancement was observed for the TPE derivative, which makes it an excellent biological fluorophores staining of intracellular DNA imaging of living cells.
