Photoinitiators (A1.3)

Project A1.3 advances photoinitiators for light-based 3D printing, expanding beyond hydrophobic systems toward aqueous-compatible, biocompatible derivatives. Building on earlier two-step, multi-color activation strategies, the project leverages photochemical action plots to design wavelength-orthogonal, synergistic, cooperative, and antagonistic reaction modes. In the next phase, these principles will guide the creation of predictive design rules and functional photoresists for multi-color, light-driven 3D printing across broad spectral ranges.
