Abstract: Described are multi-resonance-thermally-activated delay-fluorescence compounds containing (i) a polycyclic aromatic/heteroaromatic ligand in which a plurality aromatic/heteroaromatic rings are linked by boron and nitrogen atoms and (ii) an N-heterocyclic carbene ligand, with both ligands coordinated to a metal atom/ion that has a high spin-orbit coupling. The use of the high spin-orbit coupling of metals and/or metal ions facilitates the intersystem crossing and/or reversed intersystem crossing processes of MR-TADF emitters, thereby largely accelerating the rate of TADF and substantially shortening the lifetime of deleterious triplet excitons. The MR-TADF emitters can be used to fabricate blue to green emitting OLEDs.

Abstract: Disclosed are spiro-cyclometalated iridium emitters and their preparation, OLED devices including the spiro-cyclometalated iridium emitters, and methods related thereto.

Abstract: Provided herein are Ir(III) complexes comprising N-heterocyclic carbene ligand, method of synthesis of the Ir(III) complexes, a pharmaceutical composition comprises thereof. Also provided herein are the methods for the treatment and prevention of cancer/tumor in patients in need thereof by the administration of the Ir(III) complexes under both dark and light conditions. Also provided is a method of detecting the Ir(III) complex in a biological system. Also provided is a method of making the Ir(III) complex. The Ir(III) complexes possess anticancer activity such as the induction of cell death, inhibition of cellular proliferation, and inhibition of tumor growth in vivo.
