First, we investigated plasmon-assisted Z-E isomerization of free Azo molecules as a prelude to understanding this process in the hybrid material. By examining the reaction in the native Azo solvent (EtOH) we increased the temporal resolution of the measurement. In this experimental scenario, bare CNFs or Au-1-CNFs pre-composite were added directly to the Z-form of AzoGly, i.e. after UV irradiation. Temporal separation of Au addition from the UV exposure excludes possible participation of intraband excitations. Chosen irradiation conditions (650-1100 nm, 64.9 mW cm -2 ) and bare CNFs have a negligible effect on pristine Azo isomerization kinetics (Figure and Figure ). Observed differences in kZ-E values (dark vs. light conditions as well as pristine Azo vs. bare CNFs addition) are characterized by typical relative errors (see Section 5.1.
