Abstract

The use of OLEDs (organic light-emitting diodes) in display screens has become increasingly popular due to their improved energy efficiency, relatively low cost, and minimized generation of heat. For these devices, emitters with high photostabilities are desired and efforts in developing molecules of this caliber are increasing rapidly. In the work presented, treatment of an aryl-bridged, bis(N-heterocyclic thione) (NHT) pincer ligand precursor with [PdCl2(CH3CN)2] or PtCl2 yielded 6,6used ring, SCS-NHT Pd and Pt pincer complexes, which are stable in the presence of air. These complexes were found to have excellent photostabilities of 96 % and 93% retention of emission intensity, which make these complexes good candidates for uses in OLEDs. X-ray crystallography of the complexes, computational studies, and the catalytic activity of the SCS-NHT Pd complex are also reported. With advancements in photoluminescent compounds such as these, more energy-efficient display screens can be developed, reducing electricity costs world-wide.
