|Abstract: ||A set of polymers was imprinted with (−)-ephedrine using UV initiation, under
the influence of a constant external magnetic field with intensities ranging
from 0 to 1.55 T. Synthesised materials were characterised by X-ray
crystallography, infrared spectroscopy, swelling and surface area. Recognition
properties were assessed by the ability to discriminate between (+) and (−)-
ephedrine and by Scatchard analyses on chromatographic mode. It was shown that
polymer morphology and recognition properties are affected by the magnetic
field. This resulted in considerable improvements in the chromatographic
resolution of ephedrine enantiomers by materials synthesised under the influence
of magnetic field. Apparently the magnetic field improved the ordering of the
polymer structure and facilitated the formation of more uniform imprinting s|
