Abstract
Benzene vapor sorption by the organometallic coordination polymer [Zn2(bdc)2(dabco)] (H2bdc = benzene-1,4-dicarboxylic acid, dabco = diazabicyclo[2.2.2]octane) is reported. The [Zn2(bdc)2(dabco)] polymer has a high C6H6 sorption capacity of up to 3.8 mol of benzene per formula unit. The heat of sorption has been determined, and its dependence on the composition of the inclusion compound has been investigated. Included benzene molecules are nonequivalent in terms of the energy of their interaction with the metal-organic framework.
