Let’s learn more about this compound (cas:15418-29-8).
Can arsine ligands be preferred over similar phosphines to design Cu(I)-based TADF materials. The present study reveals that arsines can indeed be superior to reach shorter decay times of Cu(I) emitters. This was exemplified on bis(2-pyridyl)phenylarsine-based complexes [Cu2(Py2AsPh)2X2] (X = Cl, Br, and I), the emission decay times of which are significantly shorter (2-9μs at 300 K) than those of their phosphine analogs [Cu2(Py2PPh)2X2] (5-33μs). This effect is caused by two factors: (i) large ΔE(S1-T1) gaps of the arsine complexes (1100-1345 cm-1), thereby phosphorescence is admixed with TADF at 300 K, thus reducing the total emission decay time compared to the TADF-only process by 5-28%; (ii) higher SOC strength of arsenic (ζl = 1202 cm-1) against phosphorus (ζl = 230 cm-1) makes the kr(T1 → S0) rate of the Cu(I)-arsine complexes by 1.3 to 4.2 times faster than that of their phosphine analogs. It is also noteworthy that the TADF/phosphorescence ratio for [Cu2(Py2AsPh)2X2] at 300 K is halogen-regulated and varies in the order: Cl (1 : 1) < Br (3 : 1) ≈ I (3.5 : 1). These findings provide a new insight into the future design of dual-mode (TADF + phosphorescence) emissive materials with reduced lifetimes. As far as I know, this compound(15418-29-8)Recommanded Product: 15418-29-8 can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
