Fabricating defect-rich metal–organic frameworks via mixed linker-induced crystal transformation

Abstract

Defect-rich hcp UiO-66-NO2 was synthesized via mixed-linker induced crystal transformation from fcu UiO-66-NO2/NH2. The defect concentration and porosity of hcp UiO-66-NO2 can be fine-tuned by varying the BDC-NH2/BDC-NO2 ratio, which...

Construction of hierarchically chiral metal–organic frameworks for fast and mild asymmetric catalysis

“…57,58 Usually, two active sites are used for opening epoxide rings and their alcoholysis, as follows: (1) hydrogen bond-donating groups as Brønsted acid sites and (2) Lewis acid centers. [58][59][60][61] Most the ring-opening reactions by coordination polymers are performed employing hydrogen donatingdecorated coordination polymers or those containing open metal sites. Thus, investigating their synergistic effect on catalytic ability can be valuable to understand their co-existence.…”
