In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Reducing lifetime in Cu(I) complexes with thermally activated delayed fluorescence and phosphorescence promoted by chalcogenolate-diimine ligands, published in 2020, which mentions a compound: 15418-29-8, Name is Copper(I) tetra(acetonitrile) tetrafluoroborate, Molecular C8H12BCuF4N4, Synthetic Route of C8H12BCuF4N4.
Luminescent copper(I) complexes have drawn attention due to their promising performance as alternative optoelectronic materials to the well-known heavy transition metal complexes. Herein, we report the synthesis of six luminescent Cu(I) complexes with phosphines and 1,10-phenanthroline-derived ligands with thiadiazole and selenodiazole groups in order to evaluate the effect of the heavy atom on their photophys. properties. Steady-state and time-resolved spectroscopy confirmed delayed fluorescence emission via a thermally activated delayed fluorescence mechanism in all cases. The exptl. spectroscopic data were analyzed with detailed quantum-chem. calculations Interestingly, these complexes did not show the expected “”heavy atom effect”” that enhances the spin-orbit coupling matrix elements, but nevertheless the addition of the heavier chalcogens contributed to reducing the photoluminescence lifetime to roughly 800 ns, which is the lowest reported so far for such TADF materials.
In addition to the literature in the link below, there is a lot of literature about this compound(Copper(I) tetra(acetonitrile) tetrafluoroborate)Synthetic Route of C8H12BCuF4N4, illustrating the importance and wide applicability of this compound(15418-29-8).
