Catalysis to Improve Properties of Luminescent Materials

There is a significant demand for the design of luminescent organometallic complexes with customized properties, aimed at discovering complementary photoredox catalysts, developing enhanced lighting devices, or synthesizing specific biological probes. The electroluminescent characteristics primarily rely on the structural design of cyclometalated complexes. Building upon our catalytic approaches centered on C–H bond functionalization, we have devised novel strategies to create (fluorinated) 2-arylpyridine compounds incorporating bulky or chiral substituents. These modifications aim to enhance the properties of the corresponding iridium or platinum complexes, particularly in terms of quantum yield or circularly polarized luminescence (CPL) properties. Furthermore, we have recently revealed a groundbreaking finding that Pd-catalyzed C–H bond arylation can be directly applied to cyclometalated complexes with even greater efficiency an approach called “catalysis-on-the-complexes.”
