Anchoring and orientational wetting transitions of confined liquid crystals.

Deuterium magnetic resonance or cylindrically confined liquid crystals reveals a structural transition driven by a homeotropic-to-planar anchoring transition in the nematic phase and an orientational wetting (quasicomplete-to-partial) transition in the isotropic phase as the molecular length or the surface coupling agent is decreased. A simple phenomenological description reveals a weak positive surface order parameter in the homeotropic case and a negative one in the planar case. The absence or a symmetry breaking transition in the planar case is attributed to weak interfacial coupling
