Light‐Induced Anion Translocation to Control Helical Folding in an Artificial Communication System
Chemistry – A European Journal, EarlyView.Anion‐induced helical folding of an oligomer is controlled indirectly and reversibly by light through anion uptake/release by a photoresponsive receptor. Thus, a light signal is processed into a chemical signal in a communication‐type three‐component supramolecular system.

Towards interlocked structures based on H-bonded barbiturate complexes [PDF]
, 2010 Despite the privileged position of Hamilton’s barbiturate binding system in supramolecular chemistry, this motif has never been used in generating interlocked structures, such as rotaxanes or catenanes.

Organocatalytic Formal (3+2+1)‐Cycloaddition of Allenoates, Michael Acceptors, and Carbaldehydes
Chemistry – A European Journal, EarlyView.The use of secondary amine Lewis base organocatalysts allows for the unprecedented activation of allenoates for formal (3+2+1)‐cycloadditions with Michael acceptors and aromatic carbaldehydes. ABSTRACT Employing secondary amines as covalently interacting Lewis basic organocatalysts allows for the activation of electron‐deficient allenes (allenoates ...
