采用三聚法合成外围基团中含羟十一碳氧基的CTV衍生物(CTV-H),然后结合柱层析分离技术合成和分离出外围基团中含单甲基丙烯酸酯基团的CTV衍生物(CTV-M).以CTV-M为单体,本体聚合得到含碗形CTV侧基的甲基丙烯酸酯类聚合物(BPM).CTV-H和CTV-M都具有热致液晶性,是新的碗状液晶.SAXS和WAXD测定表明,液晶结构为六方柱相(Φh),柱直径为4.4 nm和4.8 nm,与理论计算结果相符.而BPM没有液晶性,呈非晶态.
Synthesis of CTV derivatives (CTV-H) with hydroxyl undecyloxy groups in the surrounding groups by the trimerization method and the separation of the monomethacrylate-containing groups in the surrounding groups by column chromatography CTV derivatives (CTV-M) were synthesized by bulk polymerization of CTV-M to give methacrylate polymers (BPMs) with pendant CTV-CTVs. Both CTV-H and CTV- The results show that the liquid crystal structure is hexagonal phase (Φh), the diameter of the column is 4.4 nm and 4.8 nm, which is consistent with the theoretical calculation. However, BPM has no liquid crystallinity and is amorphous .
