Self‐Photosensitizing Cobalt Complexes for Photocatalytic CO2 Reduction Coupled with CH3OH Oxidation

Angewandte Chemie, EarlyView.
Self‐photosensitizing non‐noble metal complexes achieve CO2 photoreduction coupled with CH3OH photooxidation, simultaneously synthesizing formic acid in the absence of any additional photosensitizers and electron sacrificial reductants. Abstract The use of metal complexes as homogeneous molecular catalysts has attracted considerable attention regarding

Modulare Synthese dendritischer Oligo‐Glycerin‐Kationischer Tenside zur Steigerung der antibakteriellen Wirksamkeit

Angewandte Chemie, EarlyView.
Ein orthogonaler Klick‐Chemie‐Ansatz wurde verwendet, um eine Reihe von kationischen Tensiden zu synthetisieren. Die Ergebnisse zeigen, dass ein optimales Gleichgewicht zwischen positiven Ladungen und Hydrophobizität ein entscheidender Faktor für die Verbesserung der antibakteriellen Eigenschaften ist.

Anion Recognition with Antimony(III) and Bismuth(III) Triaryl‐Based Pnictogen Bonding Receptors

Chemistry – A European Journal, Volume 28, Issue 67, December 1, 2022., 2022
A series of Antimony(III) and Bismuth(III) pnictogen bonding (PnB) triaryl‐based anion receptors demonstrate PnB anion binding strength is influenced strongly by the electronic withdrawing nature of the aryl substituent and pnictogen atom donor identity. The triaryl PnB receptors display chloride anion selectivity over a range of halides and oxoanions.
