Chemical and Physical Tailoring of Guanidine-based Covalent Adaptable Networks [PDF]
, 2022 We present the synthesis of two different guanidine-based CAN materials which, unlike traditional thermoset polymer networks, can undergo an exchange reaction called thermal guanidine metathesis (TGM) and be reprocessed.

Cross‐Dehydrogenative Coupling Reactions With Redox‐Active Guanidine Reagents
Chemistry – A European Journal, EarlyView.ABSTRACT Cross‐dehydrogenative coupling (CDC) reactions are attractive and environmentally friendly ways to form new C‐C and other element‐element bonds. Here, we report the first CDC reactions triggered by a redox‐active guanidine reagent. N‐phenyltetrahydroisoquinoline and derivatives with electron‐donating and withdrawing substituents at the N ...

Multivalent RNA‐Cleaving Agents on a Cubic Octameric Silsesquioxane Core
Chemistry – A European Journal, EarlyView.RNA‐cleaving agents on a cubic octameric silsesquioxane core were synthesized and characterized. Several catalytic systems of these structures were screened using hexaribonucleotide models. The best systems were then further used to study their catalytic efficiency in cleaving a HER2 mRNA model sequence. The induced cleavage sites were also determined.

The Radical Chemistry of 2,3‐Diguanidinopyridines: Coordination and Visible‐Light Photochemistry
Chemistry – A European Journal, EarlyView.Substitution at the pyridine core of 2,3‐diguanidinopyridines was used to develop novel redox‐active molecules with three interconvertible redox states. They are applied as redox‐active ligands in coordination chemistry. Visible‐light irradiation of the pyridine N‐benzylated molecules leads to photoconversion to a higher‐energetic isomer.
