Persistent generation of hydroxyl radicals in Tris–Co(ii) complex–H2O2 systems for long-lasting multicolored chemical lights

Abstract

Luminol tablet–Tris–Co(II) complex–PVP–H₂O₂ systems exhibit 13 hours of intensive and stable chemiluminescence (CL) due to the continuous generation of ˙OH and sustained-release. Multicolored chemical lights were prepared through CL resonance energy transfer. This work presents a new method for the fabrication of bright chemical lights in aqueous solution for emergencies.
