| 摘要 |
The development of a series of fluorescent materials including heterocycle-functionalized luminogens with aggregation-induced/enhanced emission (AIE/AEE), long wavelength emission, and high solid state fluorescence quantum efficiency is contemplated. The described fluorescent materials are promising candidates in selective luminescence-based chemosensor for Hg2+ or ATP, fluorescent staining for mitochondria in living cells with high photostability, stimuli-responsive luminescent materials, and materials for optical waveguides. In addition, these heterocycle-functionalized luminogens are particularly useful as fluorescent labels for biopolymers such as peptides, antibodies, or nucleic acids, making them useful as AIE-active biocompatible probes for clinical cancer imaging and diagnostics. |
