Abstract

New p‐cyanophenylethylpolysiloxane and p‐cyanophenylpolysiloxane stationary phases exhibiting high efficiency, cross‐Iinkability, and thermal stability up to 300°C are reported in this paper. These stationary phases possess a unique blend of polar and polarizable character that has resulted in excellent selectivities for compounds having delocalized nelectrons. Another advantage of the p‐cyanophenyl phases is their demonstrated relatively low elution temperatures for polar materials compared with the typical cyanopropyl polysiloxane phases.
