The absence of solution-state solvatochromism of the emission spectra (Figure ) is also consistent with a T1 state of LC character. This is contrast to other recently reported deepblue Ir(C^C)3 emitters mer-Ir(pmp_Bn)3 and fac-Ir(dbfmi)3 that showed significant positive solvatochromism. The similar emission spectra in MeCN and DCM solutions, and doped films suggests that there is little solvatochromism experienced by these emitters, supporting the assignment of emission from a predominantly LC excited state. a Doping concentration in vacuum-deposited films with TSPO1 as the host, b λexc = 280 nm, c Measured with an integrating sphere at 298 K under a N2 atmosphere, d Data from ref 5, e Measured in doped film (16.5 wt% in TSPO1) at 298 K using TCSPC, λexc = 379 nm, and data are extracted by using a mono-exponential decay fitting.
