Organic nano pyroelectric material and preparation method thereof

The invention provides an organic nano pyroelectric material and a preparation method thereof, and belongs to the technical field of nano medicines. The pyroelectric material provided by the invention has absorption in a near-infrared region I and a near-infrared region II, the absorption is not changed after irradiation, and the stability is high; the pyroelectric material can be subjected to photothermal conversion under the condition of near-infrared illumination; when the temperature changes, pyroelectric charges can be generated; the pyroelectric material has excellent photo-thermal conversion and pyroelectric properties, can effectively generate reactive oxygen species (ROS) to inhibit tumor cell proliferation, trigger apoptosis and kill tumors, and can induce immunogen cell death (ICD) and release damage related molecular patterns (DMAPs) including ATP, HMGB1 and CRT in the treatment process, so that T cell mediated immune response is activated, and the treatment effect is improved.
