The positively charged NiO attracts OH -ions into the IHP, which become adsorbed onto the Glotaran and the photophysical models shown in Figure . The species associated spectra from target analysis and a detailed explanation are given in the Supporting Information and Figure . Table presents the obtained lifetimes, with τ1 hole injection from P1* into the IHP and τ2 hole transfer from the IHP into the NiO. Charge recombination is assumed to occur either between P1 •-and holes localized at the NiO surface (τ3) or in the NiO bulk (τ4). The lifetimes are the longest at -0.8 V and gradually become shorter with more positive potential.
