The environmental pollution caused by the development of industry has greatly influenced human's daily life.Greenhouse effects arise from the discharge of greenhouse gases,waste and industrial sewage pollution are becoming threatens to our living environment.For purpose of solving problems,researching on selective adsorbed materials appears to be of great concern.Calixarene,hold an important position in supramolecular chemistry as their special structure,excellent host-guest recognition property and preferable thermal stability.Based on the reports about the applications in gas adsorption of Calixarene and our understanding of supermolecular,we have successfully designed and synthesized two kinds of nitro functionalized aza calixarene sorbent.Firstly,nitro group in 1,5-difluoro-2,4-dinitrobenzen activate the fluorine atom,so we could get Tetranitro-tetraazacarlix[4]arene A from an aromatic nucleophilic substitution.Secondly,using the activation of nitro group to N-H group in Tetranitro-tetraazacarlix[4]arene,we successfully prepared N-H Tetranitro-tetraazacarlix[4]arene.To study the qualifications as sorbent,we test their behavior in Gas Adsorption and Quantitative NMR Solvent Adsorption.Conclusion to the test result shows the materials exhibit admirable capacity of CO2 gas.For solvent adsorption,B possess high capacity of Ethanol,methanol and 1 4-,trans diaminocyclohexane than A because of intramolecular hydrogen bond.In all,this text introduce nitro functionalized aza calixarene as the subject investigated,we studied the gas adsorption properties and employed quantitative NMR method novelty in solvent adsorption application.This work has a inspire significance in sewage treatment and lay the foundation for development in supermolecular adsorption materials.
