SupraChem 2019

SupraChem 2019 was recently held at the Julius-Maximilians-Universität in Würzburg, Germany and organised by Florian Beuerle and Organic Chemistry Frontiers Associate Editor Frank WürthnerChemical Science was proud to support and sponsor the meeting, alongside other Royal Society of Chemistry journals Organic Chemistry Frontiers and Materials Chemistry Frontiers.

This free-to-attend meeting brought together supramolecular chemists from Germany and neighbouring countries and covered a range of topics from supramolecular machinery to materials and analytical techniques to host-guest chemistry and sensing. Keynote lectures were given by world-renowned supramolecular chemists Vivian W. W. Yang, J. Fraser Stoddart and, new Chemical Science Editor-in-Chief, Andrew I. Cooper. These speakers helped generate some great discussion alongside the additional 27 presentations and led to a very successful meeting.

Chemical Science Deputy Editor Jeremy Allen was in attendance to meet with the delegates and represent the Royal Society of Chemistry. He also helped present some poster prizes on behalf of Chemical Science and Organic Chemistry Frontiers:

  • Chemical Science poster prize winner: Jonas Matern (Universität Münster) for “Insights into the complex self-assembly pathways of a chiral, oligophenyleneethynylene (OPE) based Pd(II) complex”
  • Organic Chemistry Frontiers poster prize winner: Julia Bartl (TU Kaiserslautern) for “A cyclopeptide-derived molecular cage for anion encapsulation”

Learning from Nature: A Cu(II)-Porphyrin Complex Produces Oxygen Gas from Water at Ultra-Small Overpotential

Sunlight-assisted water splitting represents a sustainable way to convert solar energy into chemical energy in hydrogen and oxygen gases. Due to its high activation energy, the oxygen evolution reaction (OER) requires large overpotential for initiation. Developing suitable OER catalysts to reduce the overpotential thus becomes instrumental for the feasibility of solar energy harvesting.

Recently, a group of scientists led by Rui Cao from Renmin University of China, and Shaanxi Normal University, China, has developed a water-soluble Cu(II)-porphyrin complex as a high-performance OER catalyst. This breakthrough has been published in Chemical Science (DOI: 10.1039/C8SC04529A).

Inspired by the molecular structure of a natural OER catalyst in the photosynthesis system – photosystem II (PSII), the researchers designed a Cu2+-coordination compound with a porphyrin ligand, tetrakis(4-N-methylpyridyl)porphyrin (Figure 1a), which mimics the structure of PSII. This biomimetic Cu2+-complex exhibits outstanding catalytic OER activity in a phosphate buffer solution at pH=7.0. The current of the cyclic voltammogram of the Cu2+-complex increases sharply (due to O2 evolution) at an onset potential of 1.13 V vs. normal hydrogen electrode (Figure 1b), corresponding to an OER overpotential of 310 mV. For comparison, the cyclic voltammograms of a blank buffer solution and a CuSO4-containing buffer solution show no pronounced current enhancement (Figure 1b), indicating the electrolyte itself and the un-coordinated Cu2+ cannot generate O2 within the tested potential range. The 310 mV overpotential is approximately two times smaller than the typical values exhibited by previously reported Cu complexes.

Figure 1. (a) The molecular structure of Cu2+-tetrakis(4-N-methylpyridyl)porphyrin complex. (b) Cyclic voltammograms of 1 mM Cu2+-tetrakis(4-N-methylpyridyl)porphyrin (red), bare buffer solution (black) and buffer solution containing 1 mM CuSO4 (green). The electrode is a piece of fluorine-doped tin oxide glass slide.

The authors ascribed the ultra-small OER overpotential to the formation of an oxidized form of the Cu2+-porphyrin complex. This oxidized species is generated after the complex loses one electron, and is active for O-O bond formation and subsequent O2 evolution. The energy barrier of this one-electron-oxidation pathway is expected to be much lower than those of conventional processes involving higher-valent Cu species (e.g., Cu4+-oxo), which facilitates OER at small overpotential.

With the complete catalytic cycle of water oxidation by the Cu2+-porphyrin complex being fully revealed, OER will become more efficient and energy-saving.
