The March 2019 issue of MRS Bulletin focused on recent developments in porphyrin nanomaterials, and their applications in energy harvesting and biomedicine. Porphyrins are plane macrocyclic molecules containing four pyrroles connected in ring fashion through four methine carbons at their α-positions. They are present in almost all living organisms in one form or another, such as chlorophyll and heme. Porphyrins are important participants in the energy supply system for both earth and life, in the forms of photosynthesis and oxygen transport. Porphyrin nanostructures can be synthesized by self-assembly methods and have various applications including in solar-energy harvesting, water splitting, environmental pollutant reduction, and nanomedicine for tumor therapy.
This webinar expanded on the Bulletin issue, and an interactive Q&A was held with each of the speakers following their talks.
