Embodiment Construction

[0025] 1. Preparation method:

[0026] The following examples only illustrate the technical concept and characteristics of the present invention, and its purpose is to enable those familiar with the art to understand the content of the present invention and implement it accordingly, and cannot limit the protection scope of the present invention with this.

[0027] step 1: Synthesis of Triphenylamine

[0028] Under nitrogen protection at 120 °C, diphenylamine 51 g and t-BuOK 86 g and anhydrous 2000 mL DMF were stirred for 3 h. 71 g of bromobenzene was slowly added to the reaction system and stirred at 140 °C for 72 h. Then, the reaction mixture was distilled under reduced pressure, cooled, and washed with NaHCO 3 (10%) washed and extracted with petroleum ether. The organic phase was adjusted to neutral pH with MgSO 4 Dry, filter and evaporate the solvent. The remaining white crystalline product, triphenylamine, was obtained with a yield of 59 g and a yield of 80%.

Abstract

The invention relates to a synthesis method of tris-(4-tetrazolyl-phenyl)amine, belonging to the field of material chemistry. The technical scheme of the invention is as follows: reacting diphenylamine with halo-benzene under a basic condition to obtain triphenylamine, carrying out substitution reaction on triphenylamine with iodine to generate tris-(4-iodophenyl)amine, then reacting tris-(4-iodophenyl)amine with CuCN to generate tris-(4-cyanophenyl)amine, and finally reacting tris-(4-cyanophenyl)amine with sodium azide to generate tris-(4-tetrazolyl-phenyl)amine. The porous material built by reacting obtained tris-(4-tetrazolyl-phenyl)amine with a metal has the stability of carboxylic acid porous frames, achieves intra-pore functionalization, and has pores in a mesoporous size. The adsorption capacity with respect to specific sulfur-containing small molecules shows that the porous material has potential application value in developing high-performance petrochemical products.

Description

technical field [0001] The invention belongs to the field of material chemistry, and in particular relates to a synthesis method for preparing an intermediate of a class of functionalized porous materials. Background technique [0002] Waste gas environmental pollution has seriously endangered the ecological environment and human life and health, and has become one of the most serious environmental problems in the world. The main source of air pollution is the burning of fossil fuels. At present, the use of fossil energy is still dominated by combustion, and will continue for a long time. Harmful S, N, F, As, P (all contain lone pairs of electrons) and so on are converted into compounds of oxidation state - SO x , NO x , P 2 o 5 ,wait. while SO x , NO x A large amount of emission makes the air quality worsen and forms acid rain, which causes great harm to the human living environment and human beings; the corrosion damage to buildings and various facilities is very s...
