Benzene-1,3,5-tricarboxamides (BTAs) are versatile building blocks for supramolecular assembly due to the strong intermolecular hydrogen bonding. Herein, a BTA based amine, N1,N3,N5-tris(4-aminophenyl)benzene-1,3,5-tricarboxamide (TABTA), was successfully applied to construct two new amide functionalized covalent organic frameworks (COFs) with apparent crystallinity, which were further applied as efficient catalysts for Knoevenagel condensation.

Paragraph 0067; 0068; 0069, (2016/11/14)
The invention relates to a ligand used for metal-organic frameworks and a synthetic method thereof, and especially relates to a C3 symmetric aromatic tricarboxylic acid ligand, and a synthetic method thereof, and belongs to the field of organic synthesis method. The synthetic method comprises following steps: 1,3,5-benzenetricarboxylic acid chloride and paranitroaniline are subjected to amide condensation so as to obtain a nitro intermediate; the nitro intermediate is subjected to reduction so as to obtain an amino intermediate; and at last the amino intermediate and 4-benzoylbenzoic acid are subjected to aldehydeamine condensation so as to obtain the target ligand. The synthetic method is simple; yield is relatively high; reaction conditions are mild; purification is convenient; and the ligand can be used for preparation of metal-organic frameworks as a novel organic ligand, so that practical applications in the fields of gas preferential adsorption and chemical recognition are realized.

The synthesis and binding investigations of first generation C 3v-symmetrical hydrogen bonding urea-amide based tripodal receptors, 1-6, with various anions such as acetate, phosphate, sulfate and chloride in DMSO-d6 are presented. Analysis of the 1H NMR titrations of 1-6 showed on all occasions the selective formation of 1:1 stoichiometries. The Royal Society of Chemistry 2011.
