Redox-tunable pyridinium assemblies and their interactive spin-based functions

A new concept of conjugated functional assembly is proposed, leading to a g uideline for function-directed supramolecules [1] and molecular systems [2] in which the functional building units are self-assembled with considerabl e interactions among them and the whole functions more than simple sum of t he functions of the constituent blocks may be expected. The multi-mode chem ical transducer is summarized, leading to the above concept. Photo-electroc hemical spin-based function is introduced as the prototype of conjugated fu nctional assembly.
