Photoluminescent Carbon Dots
In article number 2206587, Miroslav Medveď, Giorgio Zoppellaro, Radek Zbořil, Michal Otyepka, and co‐workers report on the photogeneration of long‐lived magnetic electron/hole polaron states in aspartic acid‐based carbon dots and their use in the photoproduction of hydrogen peroxide through the water oxidation reaction. The spatial anisotropy arising from the multilayer...
Photoactivation of aspartic acid‐based carbon dots (Asp‐CDs) induces the generation of spin‐separated species, including electron/hole (e−/h+) polarons and spin‐coupled triplet states, as uniquely confirmed by the light‐induced electron paramagnetic resonance spectroscopy. The relative population of the e−/h+ pairs and triplet species depends on the solvent polarity, featuring a substantial stabilization...
