  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。
