双catenar吡啶官能化的吡唑配体[Hpz R(n,n)py ](R(n,n)= C 6 H 3(OC n H 2 n +1)2,n = 4、6、8、10、12 ,14、16、18)已战略性地合成,用作设计盘状液晶材料的新构件。它们与Pd(II)片段的配位已实现了两个新的成矿作用原家族[Pd(pz R(n,n)py)2 ](I)和[PdCl 2(Hpz R(n,n)py)](II),其中配体以阴离子形式配位为吡唑酸酯或以中性形式配位为吡唑。热学研究表明,在68–141°C的温度范围内,具有n = 14和16个碳原子的配体以及所有钯配合物均显示出盘状中间相。结果表明,金属周围的配位环境是决定中间相超分子排列的决定因素。来自复合物的盘状分子I自身堆积成圆柱结构,形成六方柱状相(Col h),而来自II的半圆盘状分子会自组装成具有反平行二聚体排列的层,该层会生成层状柱状相(Col L)。提出了

species, which were not liquidcrystals. Reactions of those diketone-based ligands with Zn(II) dichloride afforded to four new families of Zn(II) compounds. Two of them, containing the monocatenar ligands, are liquidcrystal materials, showing smectic A (SmA) mesophases and so, indicating that mesomophic behaviour is induced by complexation with the metal. However, the Zn(II) complexes carrying dicatenar

boron difluoride complexes with three (I) four (II) or five (III) peripheral chains unsymmetrically distributed, have been prepared and characterised. The thermalbehaviour was analysed in light of their molecular characteristics, allowing us to establish that the complexes of III are liquid crystal materials in contrast to the absence of mesomorphism for the related derivatives I and II. Compounds III

New dicatenar isoquinoline‐functionalized pyrazoles, [HpzR(n,n)iq] (R(n,n)=C6H3(OCnH2n+1)2; n=4, 6, 8, 10, 12, 14, 16, 18), have been strategically designed and synthesized to induce mesomorphic and luminescence properties into the corresponding bis(isoquinolinylpyrazolate)platinum(II) complexes [Pt(pzR(n,n)iq)2]. Thermal studies reveal that all platinum(II) compounds exhibit columnar mesophases over
新的双邻苯二甲酸二异喹啉官能化吡唑[Hpz R(n,n)iq ](R(n,n)= C 6 H 3(OC n H 2 n +1)2 ; n = 4,6,8,10 , 12、14、16、18)已进行了策略性设计和合成,以将介晶和发光性质诱导为相应的双(异喹啉基吡唑酸酯)铂(II)配合物[Pt(pz R(n,n)iq)2]。热学研究表明,所有铂(II)化合物在异常宽的温度范围内(大多数情况下都高于300°C)显示柱状中间相。还研究了溶液和固态下的光物理行为。由于形成了Pt·⋅·Pt相互作用,铂衍生物的弱绿色发射光在中间相中变为亮橙色。另外,配合物对多种外部输入敏感,例如温度,机械研磨,压力,溶剂和蒸汽。在此基础上,它们可用作聚乙烯吡咯烷酮或聚(甲基丙烯酸甲酯)聚合物基质的掺杂剂,以实现刺激响应性薄膜。
