R2 is selected from the group consisting of methyl; tert-butyl; prop-1-en-2-yl; dimethyl(phenyl)silyl; trimethylsilyl; diphenylmethyl; methylthio; prop-2-enyl; benzyl; ethylthio; cyclopropyl; 2-(trimethylsilyl)ethyl; 2,2-dimethylpropyl; 2-methylpropyl; phenylethyl; propyl; butyl; sec-butyl; pentyl; heptyl; propan-2-yl; cyclopentyl; cyclobutyl; 3-ethylpentan-3-yl; ethyl; 1,1-dimethylpropyl; (trimethylsilyl)methyl; trifluoromethyl; and fluoro; and
contacting the bisphenol sorbent with a sample comprising the analyte, thereby collecting the analyte,
wherein the bisphenol selectively binds with the stronger hydrogen-bond basic analyte as compared to weaker hydrogen-bond basic interferents, forming bisphenol sorbent-analyte bonds.
