报告简介:Light is of vital importance to the universe and all living beings. Generally, light is emitted from luminophores. The development of luminescent materials has thus received considerable attention and has undoubtedly promoted high-tech innovations and benefited the whole world. Aggregation-induced emission (AIE) is a unique and significant photophysical phenomenon that differs greatly from the commonly acknowledged aggregation-caused emission quenching (ACQ) observed for many π-conjugated planar chromophores. The concept of AIE was coined by our group in 2001. The AIEgens (the luminogens exhibiting AIE attributes) are non-emissive when they are genuinely dissolved in a good solvent, whereas, the emission is turned on when they are aggregated or clustered. Through systematic experimental measurements and theoretical calculations, it has been rationalized that the restriction of intramolecular motions (RIM), including rotation, vibration, stretching, etc., is highly responsible for the AIE effect. The AIEgen aggregates exhibit large absorptivity, robust luminosity, strong photobleaching resistance, no random blinking, and excellent biocompatibility. They have been widely applied for polymer topology visualization,in vitroandin vivobiosensing and imaging, micro-environment sensing, real-time organelle or cellular imaging, highly sensitive pathogen detection, long-lasting drug delivery tracking and high-resolution biological process etc.
