Abstract
The liquid chromatographic separation of basic compounds encounters often many problems related to interactions between these analytes and the usual silica-based stationary phases. In this study, the difficulty of separating sulphonium salts used in the synthesis of poly(p-phenylenevinylene) is discussed. A chromatographic system using a polymer-based column for the separation of these compounds was developed that also demonstrated the high reactivity and instability of some tetrahydrothiophenium salts.
