SUPRAMOLECULAR ARCHITECTURE
• The modern concept of Supramolecular Chemistry was introduced in 1978
by Jean-Marie LEHN, who won the Nobel Prize for his work in the area in
1987, in the words: "Just as there is a field of molecular chemistry based on
the covalent bond, there is a field of supramolecular chemistry, the chemistry
of molecular assemblies and of the intermolecular bond."
Building block - well-studied structural and functional units used to
build up larger functional architectures.
2
Tecton - molecules which play the role of building blocks in a self-
assembled, ordered supramolecular structure.1,2 A tecton is defined as “any
molecule whose interactions are dominated by particular associative forces
that induce self-asssembly of an organized network with specific
architectural or functional features”.2

SUPRAMOLECULAR ARCHITECTURE
• Metallo-supramolecular Chemistry is a term used to describe metal-
mediated self-assembly.
• the metal ions are used as templates in the organization of the molecular
building blocks and are thus chosen for their coordination numbers and
stereochemical preferences.
• the ligands are carefully designed for the formation of the synthetic target
i.e. with the appropriate use of spacer groups and the correct number and
spatial arrangement of the donor sites.
• Metal-directed self-assembly plays a key role in supramolecular chemistry
and has led to the development of an array of highly sophisticated
architectures including boxes, helicates, triangles, grids, etc.

Why ?
Asked, in 1924,
“Why ?",
George Leigh Mallory, the first great alpinist decided to climb on the top of
Everest, gave a famous answer:
“Because it exist !".
