One important objective of molecular assembly research is to create highly complex functional chemical systems capable of responding, adapting, and evolving. Therefore,we summarize an alternative approach, inspired by catalysis, to examine and describe some molecular assembly processes. A new term, ‘‘catassembly,’’ is suggested to refer to the increase in the rate and control of a molecular assembly process.
Attractive properties of polymer conductors include a wide range of electrical conductivity that can be tuned by varying the concentrations of chemical dopants, mechanical flexibility, and high thermal stability. Organic conductive materials can be grouped into two main classes: conductive polymers and conductive small molecules.
Conductive small molecules are usually used in the construction of organic semiconductors, which exhibit degrees of electrical conductivity between those of insulators and metals. Semiconducting small molecules include polycyclic aromatic compounds such as pentacene, anthracene and rubrene.
Dynamic Covalent Chemistry (DCC) is a synthetic strategy employed by chemists to make complex supramolecular assemblies from discrete molecular building blocks. DCvC has allowed access to complex assemblies such as covalent organic frameworks, molecular knots, polymers, and novel macrocycles. Not to be confused with dynamic combinatorial chemistry, DCvC concerns only covalent bonding interactions. As such, it only encompasses a subset of supramolecular chemistries.
