Thus, we defined new pairs, ON-OFF, starting from the first light period and pairing it up with the second dark interval. We modelled Ramp effect for new pairs to determine how switching the light off affects the reaction and, hence, the slope of the data. Results presented in Table -S9 and in change upon intervention, we assume that for switching light off, slope change is not as instantaneous as it is for switching light on. Due to the short lifetime of hot carriers (order of few tens of fs for Au), kinetic changes derived purely from eT and enhanced by interband excitations upon irradiation would be immediate for both types of intervention. For the thermoplasmonic effect, however, after its triggering, heat dissipation needs to occur, especially for such a complex material dispersed in water. Such a process is characterized by a much longer timeframe, and, as a result, slope change is less pronounced for shorter intervals. Thus, we can assume the dominant contribution of the thermoplasmonic effect during plasmon-assisted Azo isomerization. Therefore, we present plasmon-assisted Azo Z-E isomerization and, for the first time, the possibility of its indirect kinetic photocontrol in an ON-OFF manner via thermoplasmonic effect.
