Stable radical anions generated from a porous perylenediimide metal-organic framework for boosting near-infrared photothermal conversion

Nature Communications, 2019
Perylenediimide (PDI) radical anions show promise as photothermal agents for phototherapy, but are typically very unstable. Here the authors fabricate a PDI-based metal-organic framework where the PDI units become stable radical anions upon incorporation
