Proton-Transfer Isomerization Driven by Strong Electric Fields in Aqueous Microdroplets

-phenylenediamine quinone (6PPD-Q), which possesses a similar molecular backbone, also undergoes spontaneous isomerization in microdroplets, resulting in a significant reduction of its ecological toxicity across multiple trophic levels. This work establishes a novel platform for studying and controlling proton-transfer isomerization and offers a promising strategy for mitigating the toxicity of environmental pollutants.
