A hydrosilation reaction was used to bind four compounds with one or more alkyne groups or two alkene functionalities. The diffuse reflectance infrared Fourier transform, the 29 Si cross‐polarization magic‐angle spinning (CP‐MAS) NMR, and the 13 C CP‐MAS NMR spectra were used to characterize the various bonded materials. The bonded phase density was determined from carbon elemental analysis. The two ten‐carbon hydrophobic stationary phases were characterized chromatographically and static stability tests were run in acidic and basic solutions.
