Abstract
The invention provides organoboron precursors and facile photoirradiation and/or heating methods of making corresponding elimination products. Some elimination products are polycyclic aromatic molecules wherein a number of aromatic C—C moieties have been replaced by a B—N moiety to form azaborine compounds with interesting properties such as electronic, photophysical, luminescent, as well as chemical properties. Examples of polymer films that were doped with such compounds are shown wherein irradiated portions of the polymer film luminesce. The invention further provides methods of producing photoluminescence and electroluminescence, and uses of the compounds of the invention in luminescent probes, sensors, electroluminescent devices, hydrogen storage materials, optoelectronic materials, and bioactive molecules.
