The Metalorganic Precursor Approach

The synthesis of materials prepared from molecular components is a growing research thrust in nanomaterials science because it allows the use of molecular building blocks for the rational design and construction of new materials [42]. Novel molecular and extended networks constructed from organic and inorganic building blocks have been found to behave like molecule-based conductors and superconductors, optically active compounds, and magnets. In addition, the versatility of molecular based materials allows for the design of hybrid materials with the possibility of synergy effects. At this stage it is necessary to differentiate between the two popular strategies of obtaining materials from molecules, namely molecule-based nanomaterials (MBNs) and molecule-derived nanomaterials (MDNs). Both approaches are based on the use of molecules or molecular ions and their interactions to design a (nano)material in a bottom-up fashion. However, in the case of molecule-based materials, the molecular integrity of the building units is maintained in the final configuration (Scheme 2), whereas in the case of molecule-derived synthesis the features of the parent molecular framework are not necessarily maintained in the final material (Scheme 3).
