Effects of Strong Coupling on the Chemiluminescent Reaction of Dioxetane — •Markus Kowalewski and Mahesh Gudem — Stockholm University, Stockholm, Sweden

Chemiluminescence, seen in phenomena like firefly light emission, involves thermally activated chemical processes. Dioxetane, the smallest cyclic peroxide, exhibits chemiluminescence with a lower quantum yield than firefly dioxetane. Utilizing strong light-matter coupling as an alternative strategy, we investigate its impact on dioxetane’s chemiluminescence reaction within an optical cavity. The extended Jaynes-Cummings model is used to incorporate the cavity couplings for electronic and vibrational degrees of freedom. Results reveal that cavity interactions can either accelerate or suppress the formation of excited-state products in the dioxetane decomposition, depending on molecular orientation relative to cavity polarization.

Keywords: molecular polaritonics; strong light-matter coupling; cavity quantum electro dynamics
