The invention relates to an organic molecule, comprising or consisting of Formula A:

##STR00001## wherein M.sup.TADF represents a TADF moiety, M.sup.NRCT represents a near-range charge transfer (NRCT) emitter moiety, and L represents a divalent bridging unit that links M.sup.TADF and M.sup.NRCT and is linked to M.sup.TADF and to M.sup.NRCT via a single bond each. Furthermore, the present invention relates to the use of such organic molecule as a luminescent emitter in an optoelectronic device.

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 Some elimination products are polycyclic aromatic molecules wherein a number of aromatic CC moieties have been replaced by a BN moiety to form azaborine compounds with interesting properties such as electronic, photophysical, luminescent, as well as chemical properties.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.
