Abstract

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

Biography

A macromolecular photochemist and PhD graduate from Göttingen University, Christopher Barner-Kowollik joined the University of New South Wales in early 2000, rising to co-lead its Centre for Advanced Macromolecular Design. In 2008, he accepted a professorial chair at the Karlsruhe Institute of Technology where he established and led a German Research Council funded Centre of Excellence. In 2017, he established Queensland University of Technology’s soft matter materials laboratory, one of the world's leading photochemical laboratories. He leads and supports highly collaborative large teams and has over 280 alumni. He has authored over 750 peer-reviewed publications, which have been cited nearly 44,000 times.

Christopher's research achievements have been recognised by a wide array of national and international awards including: the Helmholtz Association’s coveted Erwin Schrödinger Award; the United Kingdom Macro Medal; the Belgian Polymer Medal; the European Polymer Federation Prize; the Australian Academy of Science’s David Craig Medal; the Royal Australian Chemical Institute; the Royal Society of New South Wales; and a professorial laureate fellowship from the Australian Research Council.
