Abstract
The current invention provides compositions, which are useful as stationary phases for a variety of chromatographic applications, such as high performance liquid chromatography (HPLC) and solid-phase extraction (SPE). The compositions provide both strong aromatic and hydrophobic interactions with components of a sample. Moreover, the invention provides compositions of new silanes, their immobilization on a solid substrate, such as silica, to form new stationary phases.
