A novel organic-inorganic hybrid material is presented containing a quenching moiety for improving the resolution of
Direct femtosecond Laser Writing by multi-photon polymerization. By exploiting the diffusion of the quencher molecule
for confining radical diffusion in the scanned area, sub-100nm resolution is achieved. 3D woodpile structures with rod
spacing of 400nm are successfully fabricated. We optically characterize these woodpiles structures and we show that
they exhibit well-ordered diffraction patterns and stopgaps down to near-infrared wavelengths.
