Objectives: This report explores the possibility of synthesizing enzyme–metal–organic framework (MOF) composites by ink-jet printing. Results: This study demonstrates that the direct synthesis of patterned enzyme–metal–organic framework (MOF) composites on various substrates including paper and polymeric films can be readily achieved by ink-jet printing bio-inks containing protein molecules, me...

Homochiral metal-organic frameworks with fine-tuned pore sizes/walls and large surface areas are promising porous materials for enantioseparation considering the traditional zeolite molecular sieves have no chirality. Using enantiopure pyridyl-functionalized salen [(N-(4-Pyridylmethyl)-L-leucine·HBr)] as a starting material, we have prepared a noninterpenetrated three-dimensional homochiral met...

Chemical clocks are often used as exciting classroom experiments, where an induction time is followed by rapidly changing colours that expose oscillating concentration patterns. This type of reaction belongs to a class of nonlinear chemical kinetics also linked to chaos, wave propagation and Turing patterns. Despite its vastness in occurrence and applicability, the clock reaction is only well u...

A metal organic framework with two different nodes (circle and square) and a structure related to one of the 20 known 2-uniform nets has been constructed using an organic building unit that codes for multiply fused nodes.

We report a hafnium-containing MOF, hcp UiO-67(Hf), which is a ligand-deficient layered analogue of the face-centered cubic fcu UiO-67(Hf). hcp UiO-67 accommodates its lower ligand:metal ratio compared to fcu UiO-67 through a new structural mechanism: the formation of a condensed "double cluster" (Hf12O8(OH)14), analogous to the condensation of coordination polyhedra in oxide frameworks. In oxi...

The first luminescent Bi-Cd-organic framework, Bi2Cd(2,6-pdc)4(H2O)2·H2O (2,6-H2pdc = pyridine-2,6-dicarboxylate), has been synthesized by using bismuth (Bi) oxides and cadmium (Cd) salts as metal sources under hydrothermal conditions. Tunable and white light luminescence was obtained through the doping of different Ln(3+) ions into the Bi-Cd-organic framework.

Aligned macroporous monoliths of an organic cage, a polymer of intrinsic microporosity (PIM-1), and a metal-organic framework (HKUST-1) are prepared by a controlled freezing approach. In addition to macropores, all the monoliths contain the intrinsic micropores.
