Abstract

The invention discloses a photothermal material, a preparation method and application thereof. The photothermal material is a co-crystal formed by a compound represented by formula (I) and a compound represented by formula (II), or the photothermal material is a compound formed by a compound represented by formula (I) and a compound represented by formula (III). Eutectic: the photothermal material can reduce the band gap through intermolecular interaction to generate photothermal effect by making the compound represented by formula (I) form a cocrystal with the compound represented by formula (II) or formula (III). The photothermal material has high photothermal conversion efficiency, can rise to 80°C within 200s under light conditions, and has good stability. At the same time, the photothermal material has the advantages of simple and efficient preparation method, smooth surface and orderly structure.

Description

technical field [0001] The present invention relates to the field of photothermal materials, in particular, the present invention relates to photothermal materials and their preparation methods and applications. Background technique [0002] Near-infrared photothermal materials have attracted extensive attention due to their properties of converting infrared light into thermal energy. Taking advantage of this feature, near-infrared photothermal materials have been widely used in photothermal therapy, photothermal imaging, photothermal sensors, seawater desalination and other fields. In order to obtain high-performance organic near-infrared photothermal materials, the traditional method is mainly to increase the near-infrared absorption and reduce the radiative transition process. At present, the most used organic photothermal dye molecules are mainly concentrated on organic dye molecules such as porphyrins, indocyanines, polyamines or polypyrroles. These organic dye molecul...
