The present disclosure features a luminescent molecule, including a luminophore (e.g., a fluorescent dye); and a moiety including a heteroaryl core covalently and directly bonded to the luminophore. The luminescent molecule has an increased photoluminescence quantum yield relative to an analogous luminophore without a covalently bonded moiety including the heteroaryl core.

caused quenching (ACQ) is reported where direct arylation is used to attach alkylated theobromine moieties onto luminophores. The resulting compounds demonstrated high photoluminescence quantum yields (PLQYs) in solution and as aggregates. The minimized ACQ can be ascribed to the large dihedral angles that theobromine moieties introduce into these molecules, preventing π–π interactions between the luminophores
