Abstract: Two Zn MOFs, MOF-645 and MOF-646, comprised of polarized 1,3-azulenedicarboxylate were synthesized. The guest free MOF-646 showed strong MOF-H2 interactions (7.8–6.8 kJ mol−1), which revealed the significant impact of internally polarized azulene backbone to stabilized H2 molecules in the framework.
