In recent years, iridium(III) complexes have been studied intensively due to their wide applications in OLEDs, biosensors, oxygen sensitizers etc. In general, there are two major kinds of iridium(III) complexes according to the category of ligands bound to Ir center: homoleptic Ir(C^N)3 and heteroleptic Ir(C^N)2(L) complexes (C^N denotes a cyclometalating ligand and L denotes an ancillary ligand). The cyclometalating ligands such as 2-phenylpyridine and its derivatives are used frequently while the most popular ancillary ligands include picolinate, acetylacetonate, and others. However, there is no study of bis-cyclometalated iridium(III) complexes with sulfur containing ancillary ligands, ( L1= 2-methylthioacetate and L2= 2-benzylthioacetate). Green-emitting Iridium(III) complexes [(ppy)2IrL1](1) and [(ppy)2IrL2](2) were synthesized from bis 2-phenylpyridine Ir(III) complex [(ppy)2IrCl]2 and the ancillary ligands. The results of our investigation including syntheses, structural characterization, thermal and luminescent properties of two new Ir(III) complexes are presented.
