Visible-light photoredox catalysis of polydopamine with triethanolamine in water.

ABSTRACT: Polydopamine (PDA), a synthetic melanin, has recently emerged as a photoreactive material, contrasting with its conventional role in photoprotection. In particular, its photochemical reactivity under visible light offers a new perspective on the role of melanin and opens up potential applications in biomedical engineering and energy conversion. However, the mechanism of the visible light-induced reactions is still not well understood, necessitating further systematic investigation. To address this challenge, we carefully investigated its photoredox catalysis under visible-light irradiation, focusing on electron transfer processes in the presence of triethanolamine as an electron donor. We explored various aspects, including its size-dependent reactivity, electrochemical and photophysical p
