In collaboration with the Flood group, we carry out CAD of small-molecule, ionic isolation lattices (SMILES). SMILES use ion-driven assembly to organize cationic dyes into a checkerboard lattice. This allows dyes to overcome the 150 year old problem of emission quenching in the solid state. Fluorescence relies on spatial and electronic isolation of the dyes. Using theory, we design, guide, and accelerate the creation of these materials. Ongoing work to discover new classes of programmable fluroescent materials (ex: charge-transfer, upconversion).
