New photoswitchable pyridyl-azo-phenyl-decorated tripodal host ligands (Laz) that belong to the cyclotriveratrylene family have been synthesized, and their photoswitching behavior and crystal structures determined. The latter includes a remarkable 7-

Four novel amino acid-functionalised triphenylenes have been prepared with glycine, L-alanine, L-phenylalanine and L-tryptophan ethyl ester side-chains. The glycine derivative is a good gelator of chloroform, the alanine derivative gels ethanol and t

(-)-Ephedrine-molecularly imprinted polymers (MIPs) have been successfully used as stationary phases in supercritical fluid chromatography for the separation of (±)-ephedrine enantiomers. This approach combines the simple preparation and predictable

The accuracy and precision of gas chromatography combustion isotope ratio mass spectrometry (GC-C-IRMS) measurements are highly dependent on analyte purity. Reliable analysis of urinary steroids for doping control therefore requires extensive and tim

Although N-isopropylacrylamide (NIPAM) has previously been used in molecular imprinting, it has mostly been considered as an ‘inert’ monomer, or included for its temperature-responsive nature, rather than as a functional monomer responsible for t

A series of molecularly imprinted polymers have been prepared and investigated as stationary phases in high performance liquid chromatography for the separation of testosterone and epitestosterone using non-polar mobile phases. The polymers were impr

Native, uncoloured, proteins can be focused in a column containing a fluorescent packing material, using hydrodynamic flow and a counteracting non-linear electric field, and imaged along the length of the channel by fluorescence quenching.

The monomers trifluoromethacrylic acid (TFMAA), 2-hydroxyethylmethacrylate (HEMA) and itaconic acid (IA) have been compared for the molecular imprinting of (-)-ephedrine. Data from NMR titrations were fitted using the program HypNMR to obtain associa

The defining characteristic of the binding sites of any particular molecularly imprinted material is heterogeneity: that is, they are not all identical. Nonetheless, it is useful to study their fundamental binding properties, and to obtain average pr

Over 1450 references to original papers, reviews and monographs have herein been collected to document the development of molecular imprinting science and technology from the serendipitous discovery of Polyakov in 1931 to recent attempts to implement
