제목 Surface-induced Phase transition of the rod-disc liquid crystal by Surface Anchoring Interactions
초록 We newly designed and synthesized molecule rod-disc liquid crystal (RD12) to characterize and understand of surface-induced phase transition behaviors of RD12 by changing the surface chemistry and the physical interaction Upon varying the LC cells thickness and their surface chemical and physical environment, the RD12 phase transition behaviors were dramatically changed compared with in the bulk. 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. The tailored molecular alignment and anisotropic physical properties of RD12 can allow us to develop the smart optical and electrical thin films for practical applications in electro-optical devices. This work was mainly supported by the Basic Science Research Program and BK21 PLUS program, Korea.
