Triethoxysilyl functionalized phenothiazinyl ureas were synthesized and immobilized by in situ synthesis into mesoporous hybrid materials . The designed precursor molecules influence the structure of the final materials and the intermolecular distance of the phenothiazines. XRD and N 2 adsorption measurements indicate the presence of highly ordered two‐dimensional hexagonally structured functional materials , while the incorporation of the organic compounds in the solid materials was proved by means of 13 C and 29 Si solid state NMR spectroscopy as well as by FT‐IR spectroscopy. Upon oxidation with (NO)BF 4 or SbCl 5 , stable phenothiazine radical cations were generated in the pores of the materials, which was detected by means of UV/Vis, emission, and EPR spectroscopies.
