N‐Heterocyclic Carbenes on a III‐V Semiconductor: From Chain Formation to Ordered Monolayers

open access: yesAngewandte Chemie International Edition, EarlyView.
The functionalization of GaAs, a model III‐V semiconductor, with N‐heterocyclic carbenes is demonstrated in a multidisciplinary experimental and theoretical approach. In this way, ordered monolayers consisting of chains of molecules binding covalently to the surface are obtained, which are found to strongly modify the surface properties as evident from

Inverting the Circularly Polarized Luminescence Handedness of Chiral Supramolecular Polymers Using Temperature

open access: yesAngewandte Chemie International Edition, EarlyView.
The supramolecular polymerization of enantiopure triarylamine trisamide monomers bearing aggregation‐induced emissive tetraphenylethene units, gave rise to a strong circularly polarized luminescence (with glum values as high as |1.8·10−2|). Strikingly, upon fast versus slow cooling rates, these monomers formed distinct hierarchical self‐assemblies (i.e.

Supercritical CO2 Sorption Within Polymers Used in Medical Devices and Their Packaging

open access: yesJournal of Applied Polymer Science, EarlyView.
In situ CO2 sorption monitoring ensured the establishment of thermodynamic equilibrium in polymers used for medical devices and their packaging. All the studied polymers, except PETG, exhibited similar kinetic profiles, allowing the quantification of CO2 sorption and the resulting polymer swelling under thermodynamic equilibrium conditions. For PETG, a
