We present the synthesis and in-depth photophys. anal. of a di-Pt(II) complex with a ditopic bis-N-C-N ligand. The complex exhibits a dual luminescent behavior by emitting simultaneously delayed fluorescence and phosphorescence. By comparing with the mono-Pt(II) analog, we demonstrate that thermally activated delayed fluorescence (TADF) is turned on in the di-Pt(II) complex due to the occurrence of three main differences relative to the mono-Pt(II) analog: a larger singlet radiative rate constant (kSr), a smaller singlet-triplet energy gap (ΔEST) and a longer phosphorescence decay lifetime (τPH). We observe similar trends among other di-Pt(II) complexes and conclude that bimetallic structures promote conditions favorable for TADF to occur. The diplatinum(II) complex also shows a long wavelength-emissive excimer which yields near IR electroluminescence, λel = 805 nm, in a solution-processed OLED device with EQEmax = 0.51%. We believe this is the highest efficiency reported to date for an excimer Pt(II) emitter with λel > 800 nm in a solution-processed OLED device.4,6-Dichloropyrimidine(cas: 1193-21-1Related Products of 1193-21-1) was used in this study.
