title: Alkynyl bridged cyclometalated Ir2M2 clusters: impact of the heterometal in the photo- and electro-luminescence properties.
abstract: We report two unprecedent alkynyl bridging cyclometalated clusters [Ir2M2(ppy)4(μ-C[triple bond, length as m-dash]CC6H4-OMe3)4] where M is Ag (2) and Cu (3), which display distinctive luminescence properties. While 2 features a green phosphorescence/electroluminescence nature located at the ppy ligands ((3)LC), 3 shows an orange emission confined to the metals and alkynyl groups having a mixed (3)L'C/(3)L'MCT/(3)MMCT (L' = alkynyl) nature.
