Nuclear magnetic resonance of confined MBBA.

Confinement of liquid crystals in small pores changes their thermodynamic, structural, and dynamical properties. In this study we are concerned with solid, liquid crystalline, and isotropic liquid phase behaviour of the nematogenic compound MBBA confined in small pores of variable diameters. Controlled Pores Glasses (CPG) were used, the morphology of these materials is a three-dimensional connected network of cylindrical pores. The present data investigates the dynamic behaviour of MBBA in porous media over the temperature range from 130 K to 330 K as a function of pores diameters.
