N2 - Nitroxide radicals, encapsulated into the cavities of metal–organic frameworks (MOFs), have recently drawn attention as multifunctional spin probes. In this work, we investigate the mobility of TEMPO nitroxide in ZIF-8 framework in the presence of various solvent molecules located in the same cavity. We employ simulations of continuous wave (CW) EPR spectra to reveal anisotropic rotation of radical. It is shown that the largest anisotropy of rotation occurs for ZIF-8 impregnated with alcohols: it is most pronounced at low temperatures, but also manifested at room temperatures. Linear alkanes do not indicate any significant effect onto the rotation anisotropy of TEMPO, while various benzene derivatives show more complicated trends caused by their bulkier shapes.
