Rod-disk liquid crystal (RD12) was newly designed and synthesized for understanding and characterizing 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 in the bulk. It was realized that the macroscopically oriented nematic (N) phase of RD12 was obtained by the surface anchoring interaction and the crystallization of RD12 was perfectly suppressed from the cross-polarized optical microscopic observations and analyses.
