제목 Surface-induced phase structures of the rod-disc molecule
초록 Upon varying the width of the LC cells and their surface chemical and physical states, the RD12 phase transition behavior was rapidly changed. Surface-induced phase transition behaviors of a rod-disc (cyanobiphenyl-triphenyl) liquid crystalline (LC) molecule (RD12) were researched by changing the surface physical and the chemical interactions. The nematic (N) phase of RD12 in the LC cell with a low cell gap and polyimide rubbed surface could be preserved and the crystallization of RD12 was completely suppressed. Based on the systematic experimental investigations, it was concluded that the glassy N phase was formed due to the fact that the surface anchoring force is bigger than the crystallization force. This work was mainly supported by the Human Resource Training Project for Regional Innovation and the Converging Research Center Program (2013K001428) of Korean government.
