Herein, we report the synthesis, structures, and magnetic properties of a series of covalent organic radical cages, generated by reducing the benzene triimide (BTI) radical precursors within the corresponding neutral cages.

In contrast, the cavity\u2010expanded cage with naphthalene bridges (7.6 \u00c5) preferentially gives a mixed\u2010valence monoradical even under excess reductant. This discrepancy originates from cavity\u2010mediated host\u2013guest interactions of the radical cages, which selectively stabilize the mixed\u2010valence monoradical of the naphthalene\u2010bridged cage. All the radical cages exhibit good stability and are characterized by single\u2010crystal x\u2010ray diffraction, EPR, and UV\u2013vis\u2013NIR spectroscopy.
