Aza-aromatic heterocycles are interesting motifs present in various photoactive molecules, however, their rational design remains challenging due to the lack of details about their excited state photophysics and photochemistry. Here, the authors combine experimental and theoretical studies of UV photoexcitation and associated relaxation dynamics for six azanaphthalenes exhibiting compositional variations, interrogating the difference in excited state lifetimes and the propensity for intersystem crossing vs internal conversion across the molecular series.
