  • 초록

    폴리(비닐 알코올)을 콜레스테릴 클로로포메이트 또는 8-콜레스테릴옥시카보닐헵타노일 클로라이드(CH8C)와 반응시킴에 의해 폴리[1-(콜레스테릴옥시카보닐옥시)에틸렌](PCOE)와 폴리[1-콜레스테릴옥시카보닐헵타노일옥시)에틸렌](PCOSE)를 합성함과 동시에 이들의 열 및 광학 특성을 검토하였다. CH8C는 단방성 콜레스테릭 상을 형성하는 반면 PCOE와 PCOSE는 쌍방성 콜레스테릭 상들을 형성하였다. CH8C의 경우와 같이, PCOSE의 광학피치 $(\lambda_m)$ 는 온도가 상승함에 따라 감소하였다. PCOE는 PCOSE와 달리 반사색깔을 나타내지 않았다. 이러한 사실은 콜레스테릴 그룹에 의한 나선의 비틀림력은 콜레스테릴 그룹과 주사슬을 연결하는 스페이서의 길이에 민감하게 의존함을 시사한다 PCOE와 PCOSE가 나타내는 액정 특성들은 폴리(콜레스테릴- $\omega$ -아크릴로일옥시알카노에이트들)이 나타내는 액정 특성들과 전혀 다르다. 이러한 결과들은 곁사슬과 주사슬의 화학결합의 양식이 콜레스테릭 상의 형성능, 안정성 그리고 $\lambda_m$ 의 온도 의존성에 중요한 역할을 함을 시사한다.


    Poly[1-(cholesteryloxycarbonyloxy)ethylene](PCOE) and poly[1-(cholesteryloxycarbonylheptanoyloxy)ethylene] (PCOSE) were prepared by reacting poly(vinyl alcohol) with cholesteryl chloroformate or 8-cholesteryloxycarbonylheptanoly] chloride (CH8C), and their thermal and optical properties were investigated. CH8C formed a monotropic cholesteric phase whereas PCOE and PCOSE exihibited enantiotropic cholesteric phases. Like in the case of CH8C, the optical pitch $(\lambda_m)$ of PCOSE decreased with increasing temperature. PCOE, contrast with PCOSE, did not display reflection colors, suggesting that the helical twisting power or the cholesteryl group highly depends on the length or the spacer joining the cholesteryl group to the main chain. The mesophase properties of PCOE and PCOSE were entirely different from those of poly $(cholesteryl-\omega-acryloyloxyalkanoates)$ . The results indicate that the mode of chemical linkage of the side chain group with the main chain plays an important role in the formation, stabilization, and temperature dependence of $\lambda_m$ of the cholesteric mesophase.
