Supramolecular chemistry is the chemistry of the intermolecular bond, covering the structures and functions of the entities formed by association of two or more chemical species.

Carbon-carbon bond formation reactions are important processes in chemistry because they provide key steps in building complex, bio-active molecules developed as medicines and agrochemicals.

Receptor chemistry, the chemistry of artificial receptor molecules, may be considered a generalized coordination chemistry, not limited to transition metal ions but extending to all types of substrates: cationic, anionic or neutral species of organic, inorganic or biological nature.

My special fascination has been to understand better the world of chemistry and its complexities.

Much of my work in biology has been driven by my early training in chemistry. When studying a new chemical compound, the first and most important thing is to determine its detailed molecular structure.

It is fortunate that molecular synthesis also serves the utilitarian function of producing quantities of rare or novel substances which satisfy human needs, especially with regard to health, and the scientific function of stimulating research and education throughout the whole discipline of chemistry.

As analytical pharmacologists, what we are allowed to see of a new molecule's properties is totally dependent on the techniques of bioassay we use.

The laws of physics should allow us to arrange things molecule by molecule and even atom by atom, and at some point it was inevitable that we would develop a technology that would let us do this.

However, it required some years before the scientific community in general accepted that flexibility and disorder are very relevant molecular properties also in other systems.
