Luminescence Vapochromism of a Cu(I)/Na Phosphane Iodide Assembly Based on a Secondary‐Sphere Sodium Response

open access: yesAngewandte Chemie, EarlyView.
The luminescence of a heterometallic d‐s {Cu2I2Na2} phosphane‐phosphinate aggregate is regulated by an interplay of Na+–π/I– contacts and reversible coordination of oxygen‐containing organic molecules to Na ions. Structural variations caused by the incoming guest lead to a wide and selective variation of the emission color and illustrate a new approach

High‐Tg Polythioesters From Isomerization Ring‐Opening Polymerization of a Renewable Oxanorbornane‐Fused Thionolactone

open access: yesAngewandte Chemie, EarlyView.
A biobased tricyclic thionolactone undergoes selective isomerization ring‐opening polymerization to yield a high‐molecular‐weight polythioester with an exceptionally high Tg of 171°C, exceeding that of the analogous polyester. The polythioester efficiently depolymerizes through backbiting, while its hydrolysis and methanolysis reveal the critical ...

Unexpectedly Strong Electrostatic Screening in Nano‐Ion Solutions

open access: yesAngewandte Chemie International Edition, EarlyView.
Colloidal probe AFM measurements reveal unexpectedly strong electrostatic screening in aqueous solutions of the polyoxometalates phosphotungstate [PW12O40]3−${[{\rm PW}_{12}{\rm O}_{40}]}^{3-}$ and silicotungstate [SiW12O40]4−$[{\rm SiW}_{12}{\rm O}_{40}]^{4-}$.
