Using an example of MOF ZIF-8 and IL [BMIm]<sup>+</sup>[BF<sub>4</sub>]<sup>−</sup>, the composites with different IL content were prepared upon control by electron paramagnetic resonance (EPR) of nitroxide spin probes. The effect of IL on the sorption of nitric oxide (II) into these composites was studied using inversion gas chromatography.</p></abstract><trans-abstract xml:lang="ru"><p id="idm45181324461792">Предложен метод контролируемого заполнения пор металл-органических координационных полимеров (МОКП) ионными жидкостями (ИЖ) для потенциального использования в селективной сорбции газов. На примере МОКП ZIF-8 и ИЖ [BMIm]<sup>+</sup>[BF<sub>4</sub>]<sup>−</sup>, с контролем методом электронного парамагнитного резонанса (ЭПР) нитроксильных спиновых зондов, приготовлены композиты с различным содержанием ИЖ.
