Preparation and sorption studies of polyester microsphere copolymers containing β-Cyclodextrin

► Polyester-based copolymers containing β-Cyclodextrin have multiple sorption sites. ► Spectroscopic and thermodynamic evidence of dual mode sorption. ► Sorption of p-nitrophenol (PNP) occurs at inclusion and interstitial copolymer sites. ► Tunable copolymer sorption occurs with PNP for incremental linker content.
