The confluence of dynamic and constitutional features
related to supramolecular self-assemblies [1-2] – when they
occur within mixtures of competing molecular architectures –
has recently opened a very intriguing branch of chemical
science, the so-called dynamic combinatorial chemistry
(DCC). Within this framework, emerging lines of
investigations have been directed towards the development of
dynamic combinatorial materials and devices. [3,4] These ones
can be defined as multi-component chemical systems which,
thanks to the reversibility of their interconnections within networks of competing reactions,
and thanks to their sensitivity to environmental parameters, aim at performing modular
functional tasks by responding to external stimuli. The behaviour of such dynamic materials is
by essence more complex than the one produced by their static or single-component
counterparts and as such, they hold higher potentialities in terms of information processing
and functionality tuning. Besides materials science, another recent approach in DCC consists
in coupling networks of reversible reactions with autocatalytic loops, in order to combine
their constitutional “plasticity” with a self-replicating process as an amplification tool. [5-7] We
will discuss some of our works concerning such responsive systems along these two different
lines and, more particularly, we will focus on their merging to access self-constructing
materials with advanced functional properties for electronic conduction. [8-10] We will also
outline the potential of such systems to act as vectors of information. [11-12]
