Programmed supramolecular system

Three levels of information input may be distinguished in self-assembly  

Molecular programming points to a molecular information science, molecular informatics and semiochemistry (see Section 8.5) involving information and signal processing and communication at the molecular and supramolecular levels (see also Section 2.1). The design of molecular information dependent, instructed and functional self-organizing systems reveals new horizons in supramolecular chemistry.

In the general context of programmed supramolecular systems, helicate formation may be described as the result of the reading by metal ions of the molecular information stored in the oligo(bipyridine) strands following a tetrahedral coordination algorithm. 

In the realm of supramolecular synthesis, the construction of rack, ladder, and grid architectures represents a particular case of self-assembly, which relies on the three basic levels of operation of a programmed supramolecular system recognition (selective interaction of complementary components) orientation (building up the stmcture through the con ect spatial disposition of the components) and termination, that is, the formation of the desired discrete supramolecular entity.
