10_03/2009Cover Picture: A Chemical System that Mimics Decoding Operations (ChemPhysChem 3/2009)

The cover picture illustrates the decoding operation that can be mimicked by a solution containing a shape-persistent macrocycle bearing two 2,2'-bipyridine units and two Coumarin 2 moieties upon chemical inputs (protons) and photophysical outputs (four protonation states of the macrocycle under UV illumination are represented in the picture). M. Venturi et al. show on p. 495 that equilibrium mixtures of protonated species of this macrocycle contain more chemical information than the sum of information carried by the individual molecules.
