  Structure and properties of novel three-armed star-shaped liquid crystals

  摘要：

  A series of novel three-armed star-shaped liquid crystals based on 1,3,5-trihydroxybenzene as a core and omega-[4-(p-alkoxybenzoloxy) phenoxycarbonyl]valeric acid as mesogenic arms were synthesized. Their chemical structures were confirmed by FTIR and H-1 NMR spectra, their mesomorphic properties and phase behavior were investigated using differential scanning calorimetry (DSC), polarizing optical microscopy (POM) and X-ray diffraction (XRD) measurements. The results show that the three-armed star-shaped liquid crystals exhibit a broad range of liquid crystalline phases at moderate temperature, no crystallization but vitrifying to form glass-forming mesogens during cooling from the isotropic melt. The formed crystals are glassy liquid crystals. The three-armed molecules are highly thermal stable and the mesomorphic ranges (Delta T) become wider as the terminal alkoxy chains become longer. Threadlike texture, a typical nematic phase, can be observed in the liquid crystalline state. (c) 2005 Elsevier B.V. All rights reserved.

  A photoactive compound is used in combination with a photosensitizer, represented by the following formula (1): A −[( J ) m −( X-Pro )] n (1) wherein A represents a hydrophobic unit comprising at least one kind of hydrophobic groups selected from a hydrocarbon group and a heterocyclic group, J represents a connecting group, X-Pro represents a hydrophilic group protected by a protective group Pro which is removable by light exposure, m represents 0 or 1, and n represents an integer of not less than 1. The protective group Pro may be removable by light exposure in association with the photosensitizer (especially, a photo acid generator), or may be a hydrophobic protective group. The hydrophilic group may be a hydroxyl group or a carboxyl group. The photoactive compound has high sensitivity to a light source of short wavelength beams, for resist application, therefore, the photoactive compound is advantageously used for forming a pattern with high resolution.

  一种光活性化合物与光敏剂结合使用，由以下公式（1）表示： A −[( J ) m −( X-Pro )] n (1) 其中，A代表至少包括一种从烃基和杂环基中选择的疏水基的疏水单元，J代表连接基团，X-Pro代表由光照可去除的保护基团Pro保护的亲水基团，m代表0或1，n代表不少于1的整数。 保护基团Pro可以与光敏剂（特别是光酸发生剂）一起通过光照可去除，也可以是疏水保护基团。亲水基团可以是羟基或羧基。光活性化合物对短波长光源具有很高的敏感性，用于光刻应用，因此，该光活性化合物有利于形成具有高分辨率的图案。

  The two series I and II of 1,1′ -disubstituted ferrocenes which differ by the direction of the ester function included in the rigid organic part were synthesized and their liquid crystal properties examined. These latter were found to be strongly dependent on the orientation of the connecting ester group and on the alkyl chain length.
