Abstract	유연격자와 메타크릴로일 기 사이에 도입된 벤젠 고리와 메소겐 구조의 말단에 연결된 키랄 중심을 갖는 새로운 두 계열의 메타크릴레이트 단량체를 합성하였다. 이 두 계열에서 유연격자와 메소겐 기의 길이 변화에 따른 액정형성에 대한 효과를 조사하였다. 첫 번째 계열의 화합물들은 합성과정에서 얻어진 중간물질이나 최종물질에서 액정성을 보이지 않았다. 그러나 두 번째 계열에서는 중간물질 뿐만아니라 최종물질에서도 액정성을 보였다. New two kinds of methacrylate monomers having a benzene ring inserted between spacer and methacryloyl group and the chiral center connected to the terminal of the mesogenic structures were synthesized. In these two series the effects for the formation of the liquid crystals in regard to the length changes of the spacers and mesogenic groups were investigated. The first series did not show any liquid crystalline phases in the intermediate compounds nor in the end products. However, the methacrylates of second series showed the liquid crystalline phases in the intermediate compounds as well as in the final products regardless of the length of the spacers.
