In a classical approach materials science is mainly dealing with
interatomic interactions within molecules, without paying much interest
on weak intermolecular interactions. However, the variety of structures
actually is the result of weak ordering because of noncovalent
interactions. Indeed, for self-assembly to be possible in soft
materials, it is evident that forces between molecules must be much
weaker than covalent bonds between the atoms of a molecule. The weak
intermolecular interactions responsible for molecular ordering in soft
materials include hydrogen bonds, coordination bonds in ligands and
complexes, ionic and dipolar interactions, van der Waals forces, and
hydrophobic interactions. Recent evolutions in nanosciences and
nanotechnologies provide strong arguments to support the opportunity and
importance of the topics approached in this book, the fundamental and
applicative aspects related to molecular interactions being of large
interest in both research and innovative environments. We expect this
book to have a strong impact at various education and research training
levels, for young and experienced researchers from both academia and
industry.
