Abstract

The invention discloses an aggregation-induced luminescent aniline derivative luminescent compound, a preparation method and an application thereof. The luminescent compound of aniline derivatives includes chemical formula I, and the corresponding luminescent compounds of aniline derivatives are B1‑A1, Br‑B1‑A1, HO‑B1‑A1, MeO‑B1‑A1 and NO 2 ‑B1‑A1. Among them, B1‑A1 and Br‑B1‑A1 do not exhibit obvious AIE characteristics, while HO‑B1‑A1, MeO‑B1‑A1 and NO 2 ‑B1‑A1 all show obvious AIE characteristics; MeO‑B1‑A1 will have obvious changes in luminescent color under the action of external force grinding, which can be used for force-responsive smart materials; NO 2 ‑B1‑A1 showed a high sensitivity response to solvent polarity changes, enabling fast, efficient and linear detection of toxic substances (trace amounts of benzene) in food-grade n-hexane.

Description

technical field

[0001] The invention belongs to the technical field of luminescent materials, and in particular relates to an aniline derivative luminescent compound with aggregation-induced emission (aggregation-induced emission, AIE) characteristics, a preparation method and application thereof. Background technique

[0002] The commonly referred to AIE phenomenon refers to the phenomenon that the luminescent material hardly emits light in a dilute solution, but emits strongly in an aggregated state. Compounds with AIE properties have fundamentally overcome the problem of aggregation caused quenching (ACQ), and have received extensive attention. However, traditional AIE molecules are mainly based on hydrocarbon chain backbones, such as triphenylethylene, tetraphenylethylene, and tetraphenyl-1,4-butadiene, while heteroatom backbone AIE molecules are rarely involved.

[0003] In fact, heteroatom-containing π-conjugated organic molecules generally have good electrochemical, ...
