Small molecule fluorescent compounds having aggregation-induced emission (AIE) characteristics are disclosed. The compounds exhibit red to near-infrared solid-state emission, large Stokes shift, high fluorescence quantum yield and good two-photon absorption cross section. The compounds can provide specific organelle staining in live cells and deep tissues. The compounds also exhibit high biocompatibility and high photostability under one-photon and two-photon continuous irradiation.
