摘要

Organic photothermal cocrystals have garnered considerable attention owing to their diverse applications in photoacoustic imaging, seawater desalination, and photothermoelectric conversion. Herein, we synthesize an organic cocrystal, Tri-F4TCNQ, which consists of a donor triphenylene and an acceptor F4TCNQ with a wide absorption wavelength range from visible light to 1800 nm. Furthermore, the Tri-F4TCNQ cocrystal has superior photothermal properties, making it highly promising for photothermal imaging applications. When illuminated with a laser of 1064 nm, the Tri-F4TCNQ cocrystal achieves a high photothermal conversion efficiency (PCE) of 63.6%, which is attributed to the dominant nonradiative pathways and suppressed radiative decay channels. Notably, the Tri-F4TCNQ crystals exhibit magnetism, and a magnetic field can effectively promote photothermal conversion. This is a highly uncommon report about magnetic-responsive photothermal effects in organic cocrystals. Moreover, the Tri-F4TCNQ cocrystal demonstrates remarkable structural stability, photosensitivity, and magnetic field responsiveness, laying a solid foundation for future applications.
