We have performed a calorimetry and deuterium nuclear magnetic resonance study for a member of the liquid crystal homologous series, n̄.O.m̄ , in bulk and confined to the 0.2 μm cylindrical pores of aluminum oxide Anopore membranes. It was shown in an ellipsometry study by Lucht and coworkers that this material shows a prewetting nematic transition at an air interface. Thermodynamically, at the Anopore solid pore walls these liquid crystals also exhibit unique wetting properties: a distinct signature in the specific heat, a "bump" at a temperature approximately 0.5 K above TNI is found. We believe that such signature is related to the manner that the nematic liquid crystal wets the solid surfaces.
