Rigid and Flexible: A Highly Porous Metal–Organic Framework with Unusual Guest‐Dependent Dynamic Behavior

A large H2 sorption capacity and high surface area are properties of the depicted metal–organic porous material, which is easily synthesized on a large scale from readily available chemicals. The rigid framework of [Zn2(1,4-bdc)2(dabco)] (1,4-H2bdc=1,4-benzenedicarboxylic acid; dabco=diazabicyclo[2.2.2]octane) is also flexible enough to exhibit unusual guest-dependent dynamic behavior, as shown (DMF=N,N-dimethylformamide).
