  探索 22 种无环尿素、咔唑和吲哚并咔唑受体对 11 种单羧酸盐的选择性

  摘要：

  羧酸盐是超分子分析化学中有吸引力的目标分析物。22 种具有不同数量和几何排列的氢键供体 (HBD) 片段和疏水部分的无环合成受体已被应用于研究 11 种碱度、疏水性和空间需求差异很大的羧酸根阴离子的实验选择性结合，从而产生 242 种准确确定的结合常数。发现除了阴离子的碱性之外，阴离子和受体的结构和空间因素也影响结合。几个有趣的案例被查明和分析。证明了所选受体根据结构特征（亲水性、α-碳取代等）区分阴离子的能力。

  The present invention relates to a process for preparing a porous material, at least comprising the steps of providing a mixture (I) comprising a composition (A) comprising components suitable to form an organic gel and a solvent (B), reacting the components in the composition (A) in the presence of the solvent (B) to form a gel, and drying of the gel obtained in step b). According to the present invention, the composition (A) comprises a catalyst system (CS) comprising a component (C1) selected from the group consisting of alkali metal and earth alkali metal salts of a saturated or unsaturated carboxylic acid and a component (C2) selected from the group consisting of ammonium salts of a saturated or unsaturated carboxylic acid and no carboxylic acid is used as a component of the catalyst system. The invention further relates to the porous materials which can be obtained in this way and the use of the porous materials as thermal insulation material and in vacuum insulation panels, in particular in interior or exterior thermal insulation systems as well as in water tank or ice maker insulation systems.

  accurately determined binding constants. It was found that besides the basicity of the anions structural and steric factors of anions and receptors influence the binding. Several interesting cases are pinpointed and analysed. The ability of selected receptors to discriminate between anions according to structural features (hydrophilicity, substitution at α-carbon, etc.) is demonstrated. The present results
