Dimeric Calix[4]resorcinarene-based Porous Organic Cages for CO2/CH4 Separation
文献摘要：
Investigating gas separation by emerging porous organic cage(POC)solids is still on its initial stage.In this work,two novel[2+4]organic cages with distinguished structures have been prepared based on the Schiff-based condensation reaction between tetraformyl-functionalized calix[4]resorcinarene building blocks and xylylenediamine(XDA)isomers.Specifically,the use of para-position XDA affords lantern-shaped cage(CPOC-105)with a medium cavity of ca.0.526 nm3,while the meta-position produces peanut-shaped structure(CPOC-106)with two small cavities of ca.0.181 nm3.Both CPOC-105 and CPOC-106 exhibit high selectivity capture of CO2 over CH4 with calculated selectivity coefficients of 4.5 and 3.1,respectively,under ambient conditions,and are capable of separating CO2/CH4 mixtures by fixed-bed column breakthrough experiments.
