Fig. 4: Effect of 365 nm UV irradiation on the thermal isomerization kinetics of AzPy in DCM.
From: A cautionary tale of basic azo photoswitching in dichloromethane finally explained
a Schematic representation of a cyclic dual pump scheme for measuring thermal isomerization kinetics of AzPy as a function of 365 nm irradiation. b Thermal isomerization kinetics of 60 μM AzPy in DCM as a function of 365 nm irradiation time. Black dashed line shows kinetic data measured after addition of PS in a 1:1 mole ratio to the final measurement sample (30 s, red curve). Each measurement was performed in duplicate. Each sample curve is normalized to its \({A}_{\infty }\) value. c Kinetic data and overlaid monoexponential fit for the black dashed curve shown in (b) plotted against x-axis extended in time. All UV-vis measurements were performed at 21 °C.
