For understanding and characterizing of surface induced phase transition behaviours of rod-disk liquid crystals by changing the surface chemistry and the physical interaction, rod-disk liquid crystal consisting of 12 carbon atoms in each alkyl chain linkage (abbreviated as RD12) was designed and synthesized. 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. 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.
