A variety of popular ionic liquids have been synthesized and characterized, including by optimized 14 N NMR spectroscopy of the neat and dissolved ionic liquids. Ionic liquids incorporating Si(OEt) 3 groups have been immobilized on silica in a well‐defined manner with the imidazolium moiety remaining intact. This has been proved by optimized one‐ and two‐dimensional 1 H and 13 C HRMAS NMR spectroscopy of the materials suspended in suitable solvents.
