A flexible friend: The electronic and structural changes undergone by Cu sites grafted inside an amorphous nanoporous P4VP matrix during a simple redox process (representing more complex liquid-phase catalysis) were investigated by complementary in situ techniques (FTIR, UV/Vis, XAS spectroscopy) (see scheme; brown Cu, green Cl, blue N, red O). The flexibility of the polymeric structure was found to be the key factor in the reversibility of the redox process.
