Aggregation-induced Emission (AIE) is a phenomenon in which some molecules do not emit light in the state of individual molecules, but can emit light in the state of aggregation. The structure of this phenomenon usually includes a rigid aromatic ring and flexible side chains. AIE technology has a wide range of applications in biological probes, optoelectronic devices, sensors and other fields, and it is a highly concerned research field.
Benzene is an important organic compound with the chemical formula C6H6, and its molecule consists of a ring of 6 carbon atoms, each with 1 hydrogen atom. Benzene is a sweet, flammable, colorless and transparent liquid with carcinogenic toxicity at room temperature, and has a strong aromatic odor. It is insoluble in water, easily soluble in organic solvents, and can also be used as an organic solvent itself. The ring system of benzene is called benzene ring, and the structure after removing one hydrogen atom from the benzene ring is called phenyl. Benzene is one of the most important basic organic chemical raw materials. Many important chemical intermediates can be derived from benzene through substitution reaction, addition reaction and benzene ring cleavage reaction.
