Rod-disc liquid crystal (LC) molecule (RD12) was newly designed and synthesized for characterizing and understanding of surface-induced phase transition behaviors of RD12 by changing the surface chemistry and the physical interactions. Upon varying the width of the LC cells and changing their surface chemical and physical states, the phase transition behavior of RD12 was rapidly changed. The nematic 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 thoroughly controlled. It was concluded on the systematic experimental investigations that the glassy nematic phase was formed because of the fact that the surface anchoring force is bigger than the crystallization force. This work was mainly supported by the Converging Research Center Program (2013K000404), and BK21 PLUS Program, Korea. |
