The most saturated green emission is present in N4 and N5. The PL lifetimes of the complexes in toluene varied widely between 0.12 and 1.78 μs, with all complexes except C3 and C4 possessing fast emission lifetimes of less than 0.90 μs. This is consistent with other moderately emissive IrPic derivatives 26 that show moderate solution-state ΦPL and short τPL.
