We compared three representation methods for the dye molecules and four for solvents. Two of the dye representations were derived from the open-source Chemprop D-MPNN framework, and we compared these representations to the ChemFluor Functionalized Structure Descriptor (FSD) representation developed by Ju et al. The FSD representation is a com-posite fingerprint created by concatenating the E-state, CDK extended, and substructure presence and count fingerprints calculated by the PaDEL software 44 through PaDELPy. Ju et al. found FSD to be superior in an extensive benchmark against other fixed fingerprint representations for predicting molecular absorption and emission peak energies. One
