A family of simple receptors formed by two or three cationic imidazolium arms attached to a central aromatic linkage and displaying different conformational flexibility has been synthesized from the enantiopure (1S,2S)-2-(1-H-imidazol-1-yl)-cyclohexanol. The crystal structures of the corresponding
Effect of solvents and beta-cyclodextrin on the absorption and fluorescence spectra of tramadol drug has been investigated and compared with anisole. The solid inclusion complex of tramadol with beta-CD is investigated by FT-IR, (1)H NMR, scanning electron microscope (SEM), DSC and semiempirical
The compound-specific mechanisms for the sorption of organic contaminants onto cetyltrimethylammonium-saturated bentonite (i.e., CTMA-Bentonite) in water were evaluated by (1)H NMR study and Linear Solvation Energy Relationship (LSER) approach. In (1)H NMR study, comparing with pure CTMAB, the
