The modification involved the epoxy ring opening of the 2\u2010biphenylyl glycidyl ether catalyzed by BF<jats:sub>3<\/jats:sub> and its subsequent reaction with the hydroxyl groups on the OHM precursor surface. The Biphenyl OHM capillary column thus obtained exhibited the typical reversed phase behavior by primarily hydrophobic interactions vis\u2010\u00e0\u2010vis the homologous series of alkyl benzenes and in addition by \u03c0\u2013\u03c0 interactions toward nitroalkane homologous series via their \u03c0\u2010electron rich nitro groups. This dual retention mechanism was very distinctly observed with a set of PAH solutes in the sense that the <jats:italic>k<\/jats:italic> values of the PAH solutes were comparable to those obtained on a more non polar stationary phase, namely the Epoxy OHM C\u201016 reported in the preceding article. Other aromatic solutes showed the dual retention mechanism on the Biphenyl OHM capillary including phenols, anilines derivatives, and phenoxy acid herbicides. The Biphenyl OHM capillary exhibited good reproducibility from run\u2010to\u2010run, day\u2010to\u2010day, and column\u2010to\u2010column.<\/jats:p>","DOI":"10.1002\/elps.201600325","type":"journal-article","created":{"date-parts":[[2016,9,9]],"date-time":"2016-09-09T13:48:19Z","timestamp":1473428899000},"page":"3172-3177","source":"Crossref","is-referenced-by-count":9,"title":["Postpolymerization modification of a hydroxy monolith precursor.
