Near-infrared (NIR) photothermal materials convert absorbed NIR light into thermal energy by inhibiting the radiative relaxation of materials. Because of the deep penetration ability, the NIR photothermal effect has been of interest in NIR laser-assisted photothermal therapy. Conventional organic NIR-absorbing molecules may not only require complex synthesis procedures, but also easily suffer from photobleaching under light irradiation. Thus, it is essential to devise an organic photothermal agent with stable photothermal capacity.

This work reported a fascinating porous perylenediimide (PDI) based metal-organic framework (MOF) Zr-PDI which can serve as cages to stabilize radical anions. Zr-PDI has high physical and chemical stability, intense near-infrared absorbance and superior photothermal conversion efficiency of 52.3%, so the work provides an efficient and simple method towards stable radical anions and affords a promising material for photothermal therapy.

Prof. Yin’s team has previously reported on other types of photothermal materials, published in Angew. Chem. Int. Ed. 2019, 58, 1638; Sci. Bull. 2018, 63, 101; ACS Nano 2017, 11, 3797, etc. 

Baozhong Lü, doctoral student, is the first author of the paper. Prof. Meizhen Yin is the corresponding author. Beijing University of Chemical Technology is the first research institution. This work was financially supported by the National Natural Science Foundation of China, the Fundamental Research Funds for the Central Universities and Research projects on biomedical transformation of China-Japan Friendship Hospital. 

Significance of this research work: This work not only provides an efficient method towards ambient stable RAs, but also gives insights into the development of novel photothermal materials
