Recent Progress In Organic High‐Temperature Photothermal Materials

Organic high-temperature photothermal materials (T > 100 °C) have demonstrated significant application values because of their ability to exceed the temperature limits of traditional organic photothermal materials, enabling spatiotemporally controllable long-distance heating and high-temperature conversion of laser or sunlight. In this review, we summarize the recent progress in organic high-temperature photothermal materials, mainly including organic small molecule and polymer materials. Their photothermal conversion mechanisms and the factors influencing their performance as well as their applications, including photo controlled ignition/deflagration, photothermal induced actuators, photo controlled metal processing, and concentrated sunlight energy conversion were elaborated. Finally, the challenges, future research directions, and potential applications are also briefly discussed.
