Abstract:

This work focuses on the design and syntheses of monovalent coinage metals based functional materials that contain potential energy applications, including energy saving, harvesting, and storage. Finding efficient, low-cost phosphorescent materials based on these late transition metal complexes has been a focal point of this study. Additionally, this has the potential to serve a number of modern display technological applications, especially inorganic and organic light emitting diodes (LEDs and OLEDs, respectively). Because of high spin−orbit coupling (SOC) induced by the coinage metal(I) centers, and high radiative triplet decay rates if applied in OLEDs, these complexes can exploit both the singlet and triplet excitons and principally, can transfer them into light with 100% internal quantum yield. The reaction of a monovalent coinage transition metal precursor with diphosphine ligands leads to the corresponding coordination complexes in high yield. These complexes exhibited blue, turquoise, and green photo luminescent emissions with high quantum yields, which are desired properties of phosphorescent materials to address the existing problems with respect to the blue-light emission of LEDs and OLEDs.
