Charge transfer cocrystals offer an opportunity to construct high performance organic photothermal materials and hold great promise toward various applications, including photothermal imaging, photothermal therapy, seawater desalination. However, the photothermal cocrystal materials are still in infancy and it is necessary to further explore them and develop more novel applications. Herein, a charge transfer cocrystal of anthracene and 7,7′,8,8′-tetracyanoquinodimethane was constructed and has a strong D−A interactions and a small HOMO−LUMO gap (1.46 eV) and thus displays a broad absorption over 300–821 nm range. The near-infrared photothermal conversion performance was evaluated under 808 nm laser illumination and the conversion efficiency reaches 58.3%, with the temperature increases to 72.1 ℃ in 145 s. The cocrystal was successfully employed as a versatile photothermal material for imaging and functional electrical device control, paving the way for the development of emerging applications in related fields.
