Abstract

The invention relates to an amphiphilic illuminant with aggregation induced emission characteristics and applications thereof. The illuminant is prepared by connecting a hydrophilia unit on a classical hydrophobicity unit of the classical aggregation induced emission characteristics (AIE), and can be applied to a fluorescent light chemical sensor and is used for preparing fluorescent light coloring agent which is used for coloring living cells and animal imaging fluorescent light. The amphiphilic coloring agent is specifically suitable for the fluorescent light mark on biopolymer, and can be used as a biocompatibility probe for AIE activation so that the amphiphilic coloring agent can be applied to clinic cancer imaging, diagnose and treatment.

Description

technical field [0001] The invention relates to the technical field of fluorescent materials, in particular to an amphiphilic luminescent substance with aggregation-induced luminescent properties and an application thereof. Background technique [0002] In recent years, it has been found that a series of helical molecules do not emit light in solution, but are induced to emit strong light after polymerization. The aggregation fluorescence quenching effect is exactly the opposite. Using this new effect, AIE luminescent materials can be applied in many high-tech fields, such as chemical sensors, biological probes, immunolabeling, stimuli-responsive materials and solid-state emitters, etc. [Chem.Commun.2001,18,1740; J.Mater.
