Such material exhibits an ultra-wide spectral range and a high extinction coefficient, and embodies excellent light absorption capacity. The strong light absorption capacity of the polymer photovoltaic material prepared by the application will help to improve the device efficiency of organic photovoltaics and improve the energy conversion efficiency of the device. The polymer photovoltaic material prepared by the application provides reference value for the design of functional materials in many fields of organic photoelectricity and solar energy utilization and conversion.

The application relates to an aryl boron compound, a preparation method and application thereof, and a pharmaceutical composition, which is used for tumor imaging, has high fluorescence quantum efficiency through intramolecular charge transfer, and can be connected to different antibodies through Q3 under a certain concentration, and can accurately target corresponding tumors according to different antibodies. The boron drug preparation can be used for boron neutron capture therapy to kill tumor cells. The compound has a better killing effect, and the compound is targeted to tumor cells through antigen-antibody interaction. After the boron-10 drug is gathered at a tumor site, neutron radiation is generated, a nuclear reaction is triggered to release alpha particles and 7 Li particles kill cells, and the ranges of the two particles are about 10 mu m. High-energy-density heavy ions break the double helix structure of DNA in tumor cells, so that the cells cannot be repaired and die completely, and the distance of 10 mu m avoids damage to normal cells and tissues.

The application discloses an aggregation-induced emission material, a preparation method and application thereof, and belongs to the technical field of preparation of the aggregation-induced emission material. The aggregation-induced emission material prepared by the application is an organic small molecule with an aggregation-induced emission effect. The fluorescent solar concentrator prepared by using the aggregation-induced emission material overcomes the problem of low efficiency of the existing fluorescent solar concentrator, and especially overcomes the problem of great efficiency attenuation caused by the increase of the device size.
