In this paper,two triphenylamine derivatives L1 and L2 were designed and synthesized with triphenylamine as raw materials,and their structures were characterized by 1H NMR and IR spectroscopy.UV-vis absorption and fluorescence emission spectra of these two complexes in ethanol-water mixture with different fraction of water were investigated.The results showed that L1 exhibited obvious an aggregation-induced emission(AIE)property,while L2 exhibited a dual-state emission(DSE)property.Cell experiments have shown that both compounds have low cytotoxicity and are capable of penetrating the cell membranes and staining cytoplasmic regions of cells,with compound L2 performing better imaging.
