This article provides a systematic summary of the latest advances in near-infrared-excited charge-transfer complexes (CTCs) as photothermal agents. The basic structure-performance relationships are introduced and several important factors affecting the photothermal properties of CTCs are discussed. Additionally, a comprehensive comparison is made among nanoparticle systems. The article highlights the multifunctional applications of organic photothermal CTCs and provides a perspective for future research.
Organic photothermal materials excited by near-infrared (NIR) light display promising applications in biomedicine, optoelectronic devices, water purification, and so on. However, the most NIR responsive organic photothermal materials are in the mire of laborious synthesis, high cost, and limited functions. The newly emerging charge-transfer complexes (CTCs) are promising photothermal materials to solve the issues and are receiving much attention. Compared with traditional photothermal agents, CTCs possess strong NIR absorption, high photo-to-thermal conversion efficiency, simple synthesis, and function-directed material design. Herein, the latest advances in NIR-excited CTCs for photothermal agents are systematically summarized. First, the basic structure-performance relationships are introduced. Then, several important factors affecting the photothermal properties of the CTCs are discussed from the sight of photophysics, and a comprehensive comparison is made among the nanoparticle systems. Finally, organic photothermal CTCs are highlighted as a multifunctional platform for applications and the perspective is given.
