    某些新型四唑液晶的合成与表征†
    摘要:
    新的4-[(2-烷基)-2 H-四唑-5-基]苯基4-烷氧基苯甲酸酯(5a-i)和5- {4-[(4-取代)苄氧基]苯基}-的合成与表征据报道有2-烷基-2 H-四唑(7a-e)。除5h和7e具有在四唑环的N -2氮原子上连接的手性香茅烷基和5i在苯甲酸酯的对位具有溴原子的5i和5e之外,所报道的四唑包含两个烷基链(六个碳原子)。通过单晶X射线分析5a和5f明确确定了烷基化步骤中的区域化学。通过分析四唑环中的C 5碳原子和附近的氮原子的亚甲基碳原子的13 C NMR化学位移,也证实了烷基化步骤中的区域选择性。液晶的介晶行为通过偏振光学显微镜(POM),差示扫描量热法(DSC)和X射线衍射(XRD)技术进行了表征。四唑基苯甲酸酯5a–h显示向列中间相。烷基链的延长有利于近晶中间相的出现。例如,5g显示向列和近晶C中间相,而具有手性香茅基的5h显示向列和近晶C中间相。四唑7a–e 没表现出介晶行为,主要是由于亚甲基取代了羰基。

    Clay-catalyzed synthesis of 5-substituent 1-H-tetrazoles
    摘要:
    Abstract magnified image In this study, the possibility of 5‐substituted 1‐H‐tetrazoles synthesis using clays as catalyst was investigated. The reaction of a series of aromatic nitriles with sodium azide was catalyzed by montmorillonite K‐10 or kaolin clays in water or DMF as solvent. Conventional heating or ultrasonic irradiation was used to promote reaction. The amount of nitrile to sodium azide mole ratio, amount of catalyst, reaction time, and solvent type were optimized. The versatility of this method was checked by using various nitriles, which showed reasonable yields of tetrazole formation. It was found that using nitriles with electron‐withdrawing groups result in both higher yields and lower reaction times. The catalysts could be reused several times without significant loss of their catalytic activity. Compared to conventional heating, ultrasonic irradiation reduced reaction times and increased catalyst activity. The present procedure is green and offers advantages, such as shorter reaction time, simple workup, and recovery and reusability of catalyst. J. Heterocyclic Chem., (2010).

The thermal properties were evaluated by TGA and DSC and indicate very thermal stable compounds. The compounds exhibited absorption in the UV-B region (∼280 nm) with
    这项工作介绍了合成和表征基于杂环三-[1,2,4]-三唑-[1,3,5]-三嗪(TTT)的化合物,该化合物可通过新的构建基块获得,可用于提供不同的一步就能制作出碟状材料。热性质通过TGA和DSC评估,表明非常热稳定的化合物。这些化合物在UV-B区域(约280 nm)具有吸收性,其摩尔吸光系数和自旋和对称性引起的辐射速率常数允许π–π *电子跃迁。观察到位于UV-A区域(约363 nm)的发射,这很可能是由于正常发射,因为没有观察到激发态的电荷转移机理的证据。旋涂膜表明存在低级烷基链的化合物中存在π堆积。循环伏安法测量显示还原和氧化过程。从对应的氧化电位获得HOMO能量,并通过从HOMO值中减去其光学带隙来找到LUMO能量。此外,由于氧化和还原电势下共轭分子电子结构的变化,采用原位UV-Vis测量来评估吸收光谱的变化。

  • Zeolite and sulfated zirconia as catalysts for the synthesis of 5-substituted 1H-tetrazoles via [2+3] cycloaddition of nitriles and sodium azide
    作者:Abbas Teimouri、Alireza Najafi Chermahini
    DOI:10.1016/j.poly.2011.07.013
    日期:2011.9
    The [2+3] cycloaddition between various nitriles and sodium azide proceeds smoothly in the presence of zeolite and sulfated zirconia as effective catalysts, in water and DMF/MeOH, to give the corresponding 5-substituted 1H-tetrazoles in good to high yields. The reaction most probably proceeds through the in situ formation of catalyst azide species, followed by a successive [2+3] cycloaddition with the nitriles. This method has the advantages of high yields, simple methodology and easy work-up. The catalyst can be recovered by simple filtration and reused with good yields. (C) 2011 Elsevier Ltd.

    The synthesis and phase behavior of three new side-chain liquid crystal polymers with short and long flexible alkyl spacers are described. These new materials show smectic C (SmC) mesophase. X-ray analysis for two samples has revealed that SmC mesophase displays partial interdigitation for the polymer with short flexible spacer, while for long flexible spacer polymer no interdigitation was observed.
