Conversion Between 2‐ and 3‐Dimensional Halogen‐Bonded Networks Formed From a Single N‐Oxide/Iodoalkyne Building Block

open access: yesChemistry – A European Journal, EarlyView.
Open halogen‐bonded networks have been prepared from building blocks that incorporate both iodoalkyne halogen bond donors and a pyridine‐N‐oxide halogen bond acceptor. An initially‐formed 3D network containing dioxane in its channels undergoes an unprecedented transition to a 2D material when crystals are exposed to diethyl ether.

Precise Control of Water Adsorption Behavior in Solid Solutions of Amorphous Coordination Polymers

open access: yesChemistry – A European Journal, EarlyView.
Amorphous coordination polymers (Am‐CPs) showed a strict modulation of water uptake behavior via a solid solution approach. The desirable water uptake characteristics were corroborated by the type and local coordination geometry of the central metals, as revealed by a combination of L2,3‐ and K‐edge X‐ray absorption fine structure (XAFS) techniques ...

Semiconducting Single‐Wall Antimony Oxide Nanotubes and Oxidotritelluridoantimonate(V) Anions

open access: yesChemistry – A European Journal, EarlyView.
Antimony(V) binds directly to tellurium(−II) in the (SbOTe3)3− anion. The latter has been found between Sb2O3 nanotubes in a microporous cetineite structure. The Sb2O3 nanotube is positively polarized on its outer surface and negatively polarized on its inner surface, corresponding to a cylindrical capacitor. Substantial charge transfer from the anions

Coordinative‐Guest‐Triggered Dimensional Crossover in a Metal–Organic Framework With Rigid Metal–Oxo Rods

open access: yesChemistry – A European Journal, EarlyView.
We report a reversible structural phase transition in a metal–organic framework (MOF) triggered by the exchange of coordinative guest molecules. This MOF consists of rigid 1D Pb–O rods as building units, forming a 3D framework with 1D pores. Guest exchange induces pronounced changes in both the Pb–O rod structure and the dimensionality of the framework.

Innovative electrospun geopolymer/zeolite/PVA composite membranes

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Proposed scheme of gas adsorption mechanisms on electrospun geopolymer/zeolite/PVA composite membranes. Abstract Innovative electrospun poly(vinyl alcohol) (PVA)–geopolymer–zeolite 13X composite membranes were successfully fabricated and systematically characterized.
