Hexagonal Nanoporous Host Structures Based on 2,4,6-Tris-4-(halo-phenoxy)-1,3,5-triazines (Halo=Chloro, Bromo)

TL;DR: In this article, a systematic analysis of six isomorphous, X-ray crystal structures (space group P63/m) provides valuable information of wide-ranging implications in host-guest chemistry: (1) construction of a host lattice with weak intermolecular interactions; correlation of guest-size and host-channel area with order/disorder in the host; role of molecular symmetry and multi-point hydrogen bond recognition for ordered guest species; unusual structural behaviour and properties of guests constrained in a narrow channel.
Journal ArticleDOI

Conversion of nonporous helical cadmium organic framework to a porous form.

TL;DR: Two novel cadmium-organic frameworks containing achiral helical nanotubular channels, [Cd(HImDC)(S)](n) (S = Im(1) and Py(2), have been synthesized and characterized using single crystal X-ray diffraction with noticeable porosity and hydrogen uptake at medium pressure.
Journal ArticleDOI

Frustrated organic solids display unexpected gas sorption.

TL;DR: From sorption studies, it is concluded that the frustrated form is porous and that the intermediate form represents a new type of material that was previously unrecognized by traditional gas sorption trends or ideals for other active systems.
Journal ArticleDOI

Gas-liquid segmented flow microwave-assisted synthesis of MOF-74(Ni) under moderate pressures

TL;DR: The metal organic framework, MOF-74(Ni), was synthesized in a continuous flow microwave-assisted reactor obtaining a high space-time yield (~90 g h−1 L−1) and 96.5% conversion of reagents as discussed by the authors.
Journal ArticleDOI

An Electrically Switchable Metal-Organic Framework

TL;DR: This letter studies the mechanism for which an electrically switchable MOF composed of Cu(TCNQ) ( TCNQ = 7,7,8,8-tetracyanoquinodimethane) transitions from a high-resistance state to a conducting state in a reversible fashion by an applied potential.
