Abstract

Three new triphenylamine derivatives bearing formyl groups were synthesized and tested for their suitability as photo-initiators for multi-photon lithography. The efficiency of the photo-polymerization was tested by two different setups and for a variety of applications. Based on their broad fabrication window, the well-defined 3D prints in the sub-micron range (resolution and aspect ratio), the solubility, we demonstrate these photo-initiators are a viable alternative to standard photo-initiators.
