Modulating H2 sorption in metal–organic frameworks via ordered functional groups†
Abstract
Herein, we present the use of presynthetic and postsynthetic modification (PSM) approaches to regulate the structural organization of functional groups in the pores of isoreticular metal–organic frameworks (IRMOFs). It has been found that the structural ordering of aryl groups within the IRMOF pores results in hysteretic H2 sorption, while the same aryl groups introduced in a disordered manner displays reversible H2 sorption that is more typical of the IRMOF family.
