| dc.description.abstract | 膽固醇液晶相可藉由在向列型液晶中摻雜少許的掌性分子而誘導出，本論文主要合成以(L)-蘇來醇衍生物為掌性中心之掌性分子，分別在(L)-蘇來醇衍生物2,3 號位置接上具有較大平面結構的OPV 基團（oligophenylenevinylene）來當作液晶原基團，此外在OPV 基團引入不同長度的碳鏈，期望液晶原基團和液晶的排列更好。結果發現接上兩個烷基化OPV 基團之掌性分子HTP 值竟可達12 左右，
和先前的實驗結果比較，摻雜未引入碳鏈之掌性分子於向列型液晶中並沒有發現膽固醇液晶相之生成，我們成功的藉由在OPV 基團中引入碳鏈，誘導出膽固醇液 晶相。 | zh_TW |
| dc.description.abstract | The cholesteric phase may be induced by the chiral dopants, which were dissolved in nematic liquid crystal. We have synthesized a series of 2,3-O-Isopropylidene-(L)-threitol derivative, modified with the oligophenylenevinylene (OPV) substituent at 2,3-position as mesogenic group. Here we modified the OPV moiety by alkylation, expecting the mesogenic group would have better alignment within the nematic liquid crystal. compared with previous results of non-alkylated OPV substituent, cholesteric phase appears when mesogenic
group with alkylation. We have successfully induced the cholesteric phase by the chiral dopants, and HTP of the chiral dopants is up to 12. | en |
