E-Zisomerization of 3-benzylidene-indolin-2-ones using a microfluidic photo-reactor

Here, we report controlledE-Zisomeric motion of the functionalized 3-benzylidene-indolin-2-ones under various solvents, temperature, light sources, and most importantly effective enhancement of light irradiance in microfluidic photoreactor conditions. Stabilization of theE-Zisomeric motion is failed in batch process, which might be due to the exponential decay of light intensity, variable irradiation, low mixing, low heat exchange, low photon fluxetc.This photo-mu-flow light driven motion is further extended to the establishment of a photostationary state under solar light irradiation.
