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.

In the search for new ligands for the Ullmanndiaryl ether synthesis, permitting the coupling of electron-rich aryl bromides at relatively low temperatures, 56 structurally diverse multidentate ligands were screened in a model system that uses copper iodide in acetonitrile with potassium phosphate as the base. The ligands differed largely in their performance, but no privileged structural class could
The preparation of the new ligand 8-(di-tert-butylphosphinooxy)quinoline (1) and the palladium derivatives [PdCl2(1)] (2), [Pd(η3-all)(1)]+ [all = C3H5 (3a), 1-PhC3H4 (3b) and 1,3-Ph2C3H3 (3c)] and [Pd(η2-ol)(1)] [ol = dimethyl fumarate (4a) and fumaronitrile (4b)] is reported. The cationic species 3a–3c have been isolated as BF4- salts. The complex 3a(BF4) is obtained either from the reaction of 1
