Abstract

The invention relates to a compound with aggregation-induced emission property as well as a preparation method and application thereof, the compound has a molecular structural formula, and R1 and R2 are respectively and independently selected from one of H and a group shown as the specification. The compound with the aggregation-induced emission property, provided by the invention, has relatively long absorption and emission wavelengths, the emission wavelength can reach a near-infrared light region, and the compound has efficient I-type ROS generation efficiency. The compound with the aggregation-induced emission property, provided by the invention, can be used for targeting tumor cell nucleus imaging after being wrapped by a cell nucleus targeting carrier to form nanoparticles. Therefore, the material can be used for tumor cell nucleus targeted photodynamic therapy.

Description

technical field [0001] The invention relates to the technical field of synthesizing multifunctional organic small molecules, in particular to a compound with aggregation-induced luminescence properties and a preparation method and application thereof. Background technique [0002] Photodynamic therapy (PDT), as a new and effective cancer treatment method, has attracted much attention due to its unique advantages of high spatio-temporal precision, controllability, non-invasiveness, and low side effects. At present, most organic photosensitizers mainly generate type II reactive oxygen species (such as singlet oxygen, 1 o 2 ) mainly, 1 o 2 The production of tumors is highly dependent on oxygen, and the hypoxic characteristics of the tumor site are not conducive to 1 o 2 The main effect of PDT is exerted, and the loss of oxygen in the process of PDT will further reduce the curative effect. [0003] Type I photosensitizers can use the dismutation reaction regulated by super...
