X-ray and SEM observations of smectic A phase and dried gel fibers formed in a fine capillary

Gel fibers of 2-oxochromen-6-yl 4-(S)-(2,6-dimethylheptyloxy) and 4-(S)-(3,7-dimethyloctyloxy)benzoates in cyclohexane were observed to grow along the surface of wall in a fine capillary. The structure of the oriented fibers was characterized by SEM and X-ray diffraction measurements, and the fiber structure was compared with the layer one in the smectic A phase.
