The application belongs to the field of organic photoelectric materials, and specifically discloses an asymmetric double free radical molecule, and the structure is: in addition, the application further discloses preparation and application of the compound. The asymmetric double free radical molecule driven by the dipole moment disclosed in the application has high stability, and the asymmetric double free radical conjugated molecule has intrinsic luminescent properties in the near-infrared two regions (monomolecular luminescence in a non-polar solvent reflects intrinsic luminescence). The application discloses that the internal dipole moment can not only regulate double free radical contribution (when the dipole moment increases to a certain degree, the double free radical index decreases, which indicates that there is a competitive relationship between charge separation and double free radical), but also affect the luminescent properties in the near-infrared two regions, and further reveal the important correlation rule of the dipole moment-free radical contribution value-luminescent properties; the application discloses that increasing the double free radical dipole moment can inhibit the general phenomenon that the molecular material emits light in the near-infrared two regions, that is, the red shift of the luminescent wavelength leads to exponential decline of the luminescent efficiency.

This invention relates to a photo-initiated method for synthesizing asymmetric azo aromatic compounds and its applications, belonging to the field of organic synthesis technology. A 1-hydroxybenzotriazole compound is deprotonated under alkaline conditions and then undergoes a cleavage reaction under visible light excitation to generate a highly reactive diradical intermediate. This intermediate is unstable and rapidly tautomerizes to a more stable nitrosophenyl anion intermediate. Under aprotic polar solvent conditions, this highly reactive intermediate is proton-quenched to obtain a highly reactive nitrosobenzene intermediate, which subsequently polymerizes with aniline compounds to generate asymmetric azo aromatic compounds. The raw materials are readily available, the synthetic route is short, the process is simple, and the products are easily separated and purified, making it suitable for large-scale synthesis. This provides a new route for the rapid preparation of asymmetric azo aromatic compounds. The synthesized asymmetric azo aromatic compounds exhibit good antibacterial activity and have significant application potential in the control of anthracnose in tea trees.
