The objectives of the ARW were: - identifying areas and
highlighting approaches by which large Supramolecular (SM)
Assemblies can be synthesised - reviewing and combining methods to
characterise and analyse such assemblies. The first part of the ARW
is devoted to reviewing synthetic achievements in recent years for
several families of SM compounds, and to bringing out principles
for crystal structure design, including novel quantum mechanical
methods. Synthesis pertains both to the chemical synthesis of
components for SM assembly, and to the subsequent assembly process
based on complementarity and non-covalent interactions. The
elaboration of multiple recognition "algorithms" concurrently
employed (for instance, 1t-1t and hydrogen bonds) has recently
reached a high degree of sophistication in the sequence: Molecules
-7 Supermolecule -7 SM array -7 Crystal or Conglomerate Novel Large
Assemblies comprise synthetic entities with molecular weight as
high as 15000, and hybrid SM assemblies between synthetic molecules
and DNA. Further developments are foreseen at a higher level of
organisation, such as between supermolecules or with
electromagnetic fields in photochemical processes. Creation of 2D
Assemblies is now a powerful tool for creation and study of SM
interactions. Moreover, much is to be learned in going from 2D to
3D assemblies in crystal growth and other forms of organisation
such as micelles or liquid crystals. On the other hand, crystal
engineering based on Molecular Recognition in the Crystal State
leads to novel 2D assemblies occurring within predesigned crystal
structures (hydrophobic organic clays or nanoporous networks).
