Abstract
We present herein new analytical protocols for the separation and structural elucidation of polyphenyls. Three commercially available chromatographic stationary phases are compared in the separation of these non-polar, unfunctionalized, positional isomers. Baseline separation of nine terphenyl and quaterphenyl isomers is achieved in under ten minutes using a rapid gradient elution HPLC method. Complete separation of these, and a further five polyphenyls, is demonstrated. We finally present a linear correlation between solvent accessible surface area and the retention times of these closely related compounds.
