Purpose of the Study:

  • To present an overview of the rational behind molecular tectonics.
  • To discuss the design and preparation of molecular networks in the solid state.
  • To highlight diverse network connectivities and topologies.

Main Methods:

  • Utilizing molecular recognition events and their iteration.
  • Employing self-assembly conditions for crystalline phase formation.
