Similar to the training set, 𝑆 1 consists of both bright and dark states in a wide variety of excitation energies within the visible range, whereas 𝑆 2 contains mostly dark states. This resulting database can then either be screened for useful candidate molecules regarding the project goal, or one can try to identify general design trends in the chemical space. For this case study, both types of analyses are briefly presented below, focusing on state 𝑆 1 specifically.
