Uniqueness of Supramolecular Systems
Macromolecular Materials and Engineering, Volume 311, Issue 5, May 2026.Thanks to the variety of classes of supramolecular systems, they have been widely used in various applications. For example, in sensing devices, catalysis, and biomedicine. An example of a conventional photovoltaic material converted into electrical energy. Selective UV or NIR absorbers are required to produce materials with low or no coloration.

European Journal of Organic Chemistry, Volume 29, Issue 16, 25 April 2026.A chemoenzymatic synthesis of (1R,2S)‐metaraminol was developed by combining gold(I)‐catalysed alkyne hydration and stereoselective biotransamination in a sequential one‐pot process. Various phenol protection strategies were considered in oxidation‐reduction sequences, providing access to enantiopure propargylic alcohols as starting materials for ...
