Poly(4‐Vinylpyridine) as Novel Organic Phase for RP‐HPLC. Unique Selectivity for Polycyclic Aromatic Hydrocarbons

Abstract

Abstract Subsidiary weak interaction such as π–π interaction shows us unique separation even in RP‐HPLC. This communication shows the first example that poly(4‐vinylpyridine) on silica provides extremely large selectivity with specificity for polycyclic aromatic hydrocarbons in methanol–water as a mobile phase. It also describes that the selectivity mode does not always obey those in conventional π‐electron‐containing stationary phases.
