Two anthracene fragments were added to a linear dioxotetramine ligand in order to exploit a [4πs+4πs] photocycloaddition reaction and obtain a photoswitchable selective receptor for CuII, whose cavity (and binding abilities) can be closed on command. Moreover, it was demonstrated that this new ligand can also be used for the photoinduced release of protons in aqueous solution, as a result of photoinduced pKa modulation.

Abstract
Two anthracene fragments were added to a linear dioxotetramine ligand in order to exploit a [4πs+4πs] photocycloaddition reaction and obtain a photoswitchable selective receptor for CuII, whose cavity (and binding abilities) can be closed on command. Moreover, it was demonstrated that this new ligand can also be used for the photoinduced release of protons in aqueous solution, as a result of photoinduced pKa modulation.File in questo prodotto:
