  卓越的双荧光，激发态分子内质子转移（ESIPT）柱状液晶，具有J堆积和大的斯托克斯位移

  摘要：

  激发态分子内质子转移（ESIPT）荧光团正在成为电子和生物技术应用中有希望的未来材料。ESIPT柱状（Col）液晶（LC）已被特别预测为先进技术的合适材料。但是，几乎没有朝这个方向进行任何探索，因此需要立即予以注意。在这里，我们报告的合成，表征和ESIPT活性的同源系列的新型Phasmidic双（N- salicylideneaniline）Col LCs的合成。光学显微镜，量热法和粉末X射线衍射（XRD）研究表明，出现了p 6 mm的六方柱状（Col h）相对称性是指，由强烈的纵向π-π相互作用促进并列排列的一对液晶元的自组装产生了组成层。X射线数据证实了切片之间没有方向相关的倾斜和柱内的横向核-核相互作用。荧光探测清楚地证明了ESIPT不仅在介晶的DCM溶液中发生，而且还在其固态，液晶和各向同性液相的三个缩合状态下发生。通常，在ESIPT现象中观察到两个原型发射带，分别在〜430 nm（弱）和〜630

  Examination of the phase transitional properties by several complementary techniques evidenced self‐assembly into a hexagonal columnar phase, occurring over wide and reasonable thermal ranges. The photophysical properties were studied both in solution and in the fluid/frozen columnar states by UV/Vis absorption and photoluminescence spectroscopy. The emission spectra obtained as a function of the temperature

  We report on the synthesis and investigation of self-assembly properties of new benzylidenehydrazine based compounds, namely N-(2,3,4-tridodecyloxybenzylidene)-3,4,5-N′-trialkoxybenzoylhydrazines. They were confirmed to exhibit wide ranges of room temperature hexagonal columnar liquid crystalline phases (Colh) as evidenced by optical polarizing microscope (OPM), differential scanning calorimetry (DSC) and X-ray diffraction (XRD) studies. Helical organization was confirmed for the Colh* phase of a compound with chiral tails. More generally, combining the 2,3,4- and 3,4,5-substitution patterns of aromatic cores in one molecule provides a new way to low melting columnar LC materials with wide phase ranges.

  我们报道了基于苄叉缩氨基脲的新化合物，即N-(2,3,4-三十二烷氧基苄叉)-3,4,5-N′-三烷氧基苯甲酰肼的自组装性质的合成与研究。通过光学偏光显微镜（OPM）、差示扫描量热法（DSC）和X射线衍射（XRD）研究证实，它们表现出广泛的室温六方柱状液晶相（Colh）。对于具有手性尾链的化合物，其Colh*相的螺旋结构得到了确认。更广泛地说，将2,3,4-和3,4,5-取代模式的芳香核结合在一个分子中，为制备具有广泛相区范围的低熔点柱状液晶材料提供了一种新方法。

  日期：2006.10

  A series of unsubstituted and 1,4-disubstituted gallic catecholates 1, 6 and 7 as possible candidates for wedge-shaped mesogens were prepared starting from the respective benzene derivatives 2a-c and gallic esters 5a-h. The mesomorphic properties were investigated by DSC. However, only the 4,5-dinitro derivatives 1d,f-h with C8H17 and C10H21 to C12H25 alkyl side chains displayed mesophases, as evaluated by fluidity and optical anisotropy. (c) 2006 Elsevier Ltd.
