Reinventing Chemiluminescence through Redox-Driven Self-Assembly.

ABSTRACT: Chemiluminescence (CL) typically derives from harvesting the energy released during the cleavage of covalent bonds, wherein molecular substrates are irreversibly consumed to generate electronically excited states. In contrast, regenerative CL seeks to bypass substrate decomposition by using reversible redox processes to produce emissive states, an approach that is largely limited to polypyridyl complexes of Ru(II) and Cr(III). Here, we report a fundamentally distinct chemiluminescence mechanism in which the exergonic reduction of Pt(IV) complexes powers the spontaneous formation of emissive Pt(II) aggregates. Notably, light emission arises not from discrete molecular species but from the self-assembled state, whose electronic structure features a lowered excited-state energy (E
