Molecular Recognition
We explore macrocyclic receptors for sensing biologically and industrially relevant species. We have pioneered the development of a new family of cationic macrocycles termed pillar[n]pyridiniums. These compounds, both independently and in conjunction with gold nanoparticles, exhibit remarkable discriminatory abilities across a wide range of anions, including:
- positional isomers
