Abstract

We present an efficient method for surface customization using a novel D–π–A-based photosensitive alkoxyamine. The D–π–A-based chromophore group exhibits remarkable efficiency in the homolytic cleavage of the >NO–C bond enabling the production of well-defined structures through two-photon stereolithography (TPS). Furthermore, we show that surface customization can be achieved in a second step, owing to the “living” character originating from the alkoxyamine and via a Nitroxide Mediated PhotoPolymerization (NMP2) process. Additionally, we investigated how TPS-related parameters such as wavelengths and laser power influence the re-polymerization step.
