This work reports a rare radical-doped metal–organic framework (MOF) crystal with one-dimensional open channels achieved by coordination-driven self-assembly. X-ray single-crystal diffraction, solid-state UV–vis–NIR diffuse reflectance spectroscopy, and electron paramagnetic resonance analysis were used to clarify its unique structure why many organic radicals stably exist in the lattice. The study shows that this has strong intermolecular cofacial π–π interactions, narrow optical bandgap (only 1.47 eV), low LUMO, shallow HOMO. These features allow an inherent charge transfer, leading genetation of under ambient conditions. Interestingly, post-treatment can effectively adjust MOF. Mechanical grinding quickly reduces number radicals. Then, soaking sample N,N-dimethylformamide solution diphenylamine, para-methylaniline, or carbazole (as donors), physically these amine molecules, recover reduced some degree.

Charge-assisted photochromic iHOF-51 enables fast stimulus-responsive behavior through photogenerated anionic radicals. Time-dependent photochromism in the powder form and FRET-based photoluminescence composite membranes are observed.
