Strategic Analysis for Photophysical Properties of Organometallic Luminophores

The development for novel organic/organometallic luminophores has led to considerable research into efficient functional materials for prominent optoelectronic applications. Among them, o -carborane ( closo -1,2-C 2 B 10 H 12 ) containing organic fluorophores and iridium(III)-cyclometalate phosphores have been widely researched as unprecedented optoelectronic materials for a variety of photonic applications. Such the organometallic complexes exhibit unique luminescent behaviours based on structural geometry and electronic environment of the π -conjugated aromatic ligands appended to the o -carborane and Ir(III). In line with exploring the relationship between their intramolecular photophysical characteristics and the structural or electronic features, various o -carboranyl fluorophores and Ir(III)-cyclometalate phosphores were strategically designed, prepared and their photophysical properties were analysed in detail.
