1Mesomorphic behavior of new benzothiazole liquid crystals having Schiff base linker and terminal methyl group显示文摘heterocycles 的一个相应系列, 6-methyl-2-(4-alkoxybenzylidenamino ) benzothiazoles,被综合并且描绘了使用英尺红外, 1H 和 13C NMR 和集体度谱的分析。二形互变的 nematic 阶段为更矮的成员被观察。近晶的 A 阶段仅仅向前从 octyloxy 衍生物出现了。在 benzothiazole 碎片和 Schiff 基础连接的终端甲基组影响了现在的系列的具有由中胚叶发达的行为。Sie Tiong Ha Kok Leei Foo Hong Cheu Lin Masato M.Ito Kazuma Abe Kenji Kunbo S.Sreehari Sastry 2012Chinese Chemical Letters2012,23,7:2
2Novel alternating fluorene-based conjugated polymers containing oxadiazole pendants with various terminal groups显示文摘Sung Haiso Hsien Lin Hong Cheu 2004Macromolecules2004,37,21:1
3Synthesis and mesomorphic properties of Schiff base esters possessing terminal chloro substituent显示文摘A homologous series of Schiff base esters, 4-chlorobenzylidene-4'-n-alkanoyloxyanilines, containing even number of carbons at the end groups of the molecules (Cn-1H2n-1COO-, n = 4,6,8,10,12,14,16) were synthesized. The mesomorphic properties were investigated by differential scanning calorimetry (DSC) and polarizing optical microscopy (POM). It was found that the end groups of the molecules had an effect on the mesomorphic properties. n-Butanoyloxy was found non-mesogenic, whilst n-hexanoyloxy exhibited monotropic smectic phase. The higher members in this homologous series were enantiotropic smectogens.Sie Tiong Ha Lay Khoon Ong Siew Ling Lee Hong Cheu Lin Yip Foo Win Siew Teng Ong 2010Chinese Chemical Letters2010,21,6:1
4Synthesis and characterization of kinked and hyperbranched carhazole/fluorene based copolymers显示文摘Wu Chung Wen Lin Hong Cheu 2006Macromolecules2006,39,21:1
5Synthesis and characterization of poly(fluorene-co-alt-phenylene) containing 1,3,4-oxadiazole dendritic pendants显示文摘Wu Chung Wen Sung Hsiao Hsien Lin Hong Cheu 2006J Poly Sci Part A: Polym Chem2006,44,:1
6New mesogenic Schiff base esters comprising benzothiazole moiety:Synthesis and mesomorphic properties显示文摘Schiff 基础酉旨的一个相应系列, 6-methoxy-2-(2-hydroxy-4-alkanoyloxybenzylidenamino ) benzothiazoles,作为核心包括 benzothiazole 一半被综合。这个系列的所有成员展出了一个二形互变的 nematic 阶段。与侧面的氢氧根和终端 methoxyl 组一起的 azomethine 连接被发现在具有由中胚叶发达的性质上施加效果。Sie Tiong Ha Teck Ming Koh Guan Yeow Yeap Hong Cheu Lin Jun Kit Beh Yip Foo Win Peng Lim Boey 2009Chinese Chemical Letters2009,20,9:0
7Synthesis and mesomorphic evaluation of new calamitic liquid crystals containing benzothiazole core显示文摘新 calamitic 的设计和合成基于 benzothiazole 的液体晶体, 2-[4-(4-alkyloxybenzoyloxy )-phenyl]benzothiazoles 被介绍。目标混合物用分光镜的技术被描绘,例如英尺红外, NMR (1H 和 13C ) ,微量分析和 EIMS。液体这些混合物的水晶的行为被微分扫描热量测定彻底地检验并且极化光显微镜技术。这些材料与高热的稳定性展出了二形互变的 nematic 阶段(> 168 牢畩 ? 潣獮慴瑮 ? 牡 ????????? 湡 ? ㈱? 祝 ? 潭 ?? 愠摮琠敨洠汯牡攠瑮慨灬 ? 景戠湩楤杮愠敲ㄠ ??? ㄠ ??? 湡 ???? 欠 ? 潭 ? 愠 ???????? 愠摮 ??? ‵?爠獥数瑣癩汥 吗?Teck Ming Koh Sie Tiong Ha Teck Leong Lee Siew Ling Lee Guan Yeow Yeap Hong Cheu Lin Ramesh T.Subramaniam 2011Chinese Chemical Letters2011,22,5:0
8Synthesis and mesomorphic properties of new Schiff base esters with different alkyl chains显示文摘Schiff 基础酉旨的一个新系列,4-( dimethylamino ) benzylidene-4′ ;在分子的结束组的碳的 -alkanoyloxyanilines 包含偶数( C n− ; 1 H 2n−1咕咕叫, n = 6 , 8 , 10 , 12 , 14 , 16 , 18 )被综合。现在的混合物是单音的回归线液体晶体。分子的结束组在具有由中胚叶发达的性质上有效果,这也被发现。Sie Tiong Ha Lay Khoon Ong Siew Teng Ong Guan Yeow Yeap Joanna Pik Wan Wong Teck Ming Koh Hong Cheu Lin 2009Chinese Chemical Letters2009,20,7:0
