主　　题：adsorption hydrocarbons separation 

摘      要：Adsorption and separation of C_(4) hydrocarbons are crucial steps in petrochemical *** of porous materials for enhancing the separation efficiency have paid much ***-organic frameworks of diamond-topology,dia-COFs,often exhibit unique structural properties such as interpenetration isomerism and pedal ***,in order to get a deep insight into the structure-performance correlation of such dia-COFs,a series of dia-COF materials have been proposed and theoretically investigated on the C_(4) *** is found that these dia-COFs display an excellent adsorption and separation property towards isobutene with respect to other C_(4) hydrocarbons(i.e.,1,3-butadiene,1-butene,2-cis-butene,2-trans-butene,isobutane and n-butane).What’s more,the correlation between the topology parameters and experimental synthesis feasibility has been established for COF-300(dia-cN),and the unreported COF-300(dia-c3) is predicted to be experimentally feasible *** findings not only provide a deep insight into the mechanism of topology characteristics of dia-COFs on C_(4) adsorption and separation properties but also guide the design and synthesis of novel highly-effective porous materials.
