Inside Cover: Polydopamine as a Biomimetic Electron Gate for Artificial Photosynthesis (Angew. Chem. Int. Ed. 25/2014)
The role of mussel-inspired polydopamine (PDA) as an electron gate and a versatile adhesive for mimicking natural photosynthesis is described in the Communication by C. B. Park and co-workers on page 6364 ff. The introduction of PDA as a charge separator significantly increased the rate of photochemical water oxidation by efficient and forward electron transfer. Furthermore, simple incorporation of a PDA ad-layer on the surface of conducting materials also facilitated fast charge separation and oxygen evolution.
