Orthogonal, Synergistic and Cooperative Precision Photochemistry for Multi-Wavelength Additive Manufacturing

Over the last decade, our laboratory has employed monochromatic tunable laser systems to reveal a fundamental mismatch between the absorptivity of a chromophore and its photochemical reactivity in the vast majority of covalent bond forming reaction as well as specific bond cleavage reactions. Our data overturns the long-held paradigm that effective photochemical reactions are obtained in situations where there is strong overlap between the absorption spectrum and the emission wavelength. The lecture will demonstrate how a detailed action-plot driven precision mapping of photochemical reactivity enables the design of advanced multi-colour network formation and 3D printing modes with never-before-seen precision, exploiting wavelength orthogonal, synergistic, cooperative, and antagonistic photochemical reaction systems.
