Metallated Schiff-Base Macromolecules as Alternative Metalloprotein Electron Transfer Intermediates

Upon the gradual addition of Al3+ to a solution of HL, the sensor showed a large fluorescence enhancement at 420 nm. The reason for this phenomenon is that the addition of Al3+ to the solution of HL results in the formation of a 1 : 1 stoichiometry of the binding mode of L–Al which inhibits photoinduced electron transfer (PET).

Chiral Schiff Base

The oxygen reduction efficiency of a laccase-modified electrode was found to depend on the chirality of the oligopeptide linker used to bind the enzyme to the surface. At the same time, the electron transfer between the cathode electrode and the enzyme is improved by using a copper(II) complex with amino-acid derivative Schiff base ligand with/without azobenzene moiety as a mediator. The increased electrochemical current under both O2 and N2 proves that both the mediators are active towards the enzyme.
