  摘要：

  在基于聚合物的离子导体中，电导率由于链迁移率低而受到抑制，因此必须设计一种分子系统，其中离子基团可以随温度而动员和固定，以允许离子自由移动以及以低能量屏障的受控方式。在本文中，我们报告了一种创新的方法，可以结合功能化分子的自组装和拆卸概念来研究无水离子（质子）传导和相关活化能（E a）。为此，以如下方式设计有机质子导体：分子的自组装可以通过非共价相互作用发生，从而产生将离子基团保持在一起的有组织的固态通过氢键网络。为燃料电池应用研究了一种新型的具有疏水性和亲水性对应物的无水离子导体，分别是烷基链和膦酸基团。这些离子分子的最高无水质子电导率在140°C时高达10 -2 S cm -1。这些材料的热重分析表明，它们在高达190°C的温度下具有稳定性，因此具有在高温下运行的能力。

• Discotic metallomesogens: mesophase crossover of columnar rectangular to hexagonal arrangements in bis(hydrazinato)nickel(II) complexes

  Three series ofN-(3,4-dialkoxybenzylidene)-N′-(3′,4′,5′-trialkoxybenzoyl)hydrazine and their nickel(ii) complexes, bis[N-(3,4-dialkoxybenzylidene)-N′-(3′,4′,5′-trialkoxybenzoyl)hydrazinato]nickel(ii), were prepared and characterized. The mesomorphic properties of these disc-like compounds were also studied in terms of liquid crystallinity. The orange nickel(ii) complexes with ten soft alkoxy side chains exhibited columnar disordered mesophases, which were characterized based on DSC analysis and optical polarized microscopy. Nickel complexes with shorter side chains (n=5–8) displayed a monotropic columnar rectangular disordered (Colrd) phase; however, complexes with longer side chains showed monotropic (n=10) and enantiotropic (n=12, 14) columnar hexagonal disordered (Colhd) phases. Similar nickel complexes (n=14) with eight side chains exhibited a columnar hexagonal phase, whereas complexes (n=14) with six side chains formed crystalline phases. The structures of these columnar disordered phases were confirmed by X-ray powder diffraction. XRD data indicated that mesophase crossover from columnar rectangular (Colr) to hexagonal arrangements (Colh) was observed with increasing side chain lengths.
