In this work. we report a series of bis-tridentate Ir(III) metal complexes. comprising a dianionic pyrazole-pyridine-phenyl tridentate chelate and a monoanionic chelate bearing a peripheral carbene and carboline coordination fragment that is linked to the central phenyl group. All these Ir(III) complexes were synthesized with an efficient one-pot and two-step method. https://www.isyeriacilisi.com/product-category/tea-coffee-and-sweetners/
