  Symmetrical mesogenic 2,5-bis(6-naphthalen-2-yl)-1,3,4-thiadiazoles

  摘要：

  Two series of new symmetrical 1,3,4-oxadiazoles 1a-n and 1,3,4-thiadiazoles 1b-n were prepared and their mesomorphic properties investigated by optical microscopy, differential scanning calorimetry, and powder X-ray diffractometry. Compounds 1b-n are kinetically more stable than compounds 1a-n. Compounds 1a-n exhibited monotropic nematic or smectic C phases, whereas, compounds 1b-n exhibited enantiotropic nematic or smectic A/smectic C phases. Compounds 1b-n have higher clearing temperatures and the larger temperature ranges of mesophases, which might be attributed to the better linearity and/or larger dipole, resulted from a more polarized sulfur atom than oxygen atom incorporated. The fluorescent properties of these two series of 1,3,4-thiadiazole/oxadiazole-based derivatives were also examined. The lambda(max) peaks of the photoluminescence spectra for compounds 1a-6 and 1b-6 measured in THF occurred at ca. 385 nm and 423 nm, respectively. Both series were blue emitters.

  来自水杨醛亚胺的对称介晶双胞胎

  摘要：

  据报道，一系列衍生自介晶水杨醛亚胺1a – e的对称二聚体孪晶的合成，表征和同构性质。为了理解结构与属性的关系，系统地改变了桥间隔基（m = 5、6、7、8、9 ）和烷氧基链（n = 6、8、10、12、14）。除1a以外，所有衍生物1b – e均表现出中间相，其介晶性质强烈依赖于间隔基团和烷氧基链。二聚体1a表现出结晶或SmX相。其他二聚体1b – e具有真正的介晶作用，提供对映SmC，SmA或/和N相。在相温上观察到奇偶效应，对于带有奇数间隔基的衍生物观察到向列相，d / l = 0.92（1a ; m = 5，n = 8）–0.84（1c ; m = 7，通过粉末X射线衍射数据获得n＝ 14），因此提出了中间相的单层结构。
