Decreasing the structure dimensions leads to an increasing depletion of the deficient ene groups in the non-illuminated region in 80% OSTE. (a) Schematic cross-section of the photostructuring. (b) The corresponding confocal Raman microscopy images of unreacted thiol groups in large-diameter (125 µm) and small-diameter (30 µm) features. (c) Measured ratio of unreacted thiols over enes as a function of the feature radius.
