A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 13991-08-7, Name is 1,2-Bis(diphenylphosphino)benzene, molecular formula is C30H24P2. In a Article，once mentioned of 13991-08-7, COA of Formula: C30H24P2
Dinuclear Cu(I) Complex with Combined Bright TADF and Phosphorescence. Zero-Field Splitting and Spin-Lattice Relaxation Effects of the Triplet State
The three-fold bridged dinuclear Cu(I) complex Cu2(mu-I)2(1N-n-butyl-5-diphenyl-phosphino-1,2,4-triazole)3, Cu2I2(P^N)3, shows bright thermally activated delayed fluorescence (TADF) as well as phosphorescence at ambient temperature with a total quantum yield of 85% at an emission decay time of 7 mus. The singlet (S1)-triplet (T1) energy gap is as small as only 430 cm-1 (53 meV). Spin-orbit coupling induces a short-lived phosphorescence with a decay time of 52 mus (T = 77 K) and a distinct zero-field splitting (ZFS) of T1 into substates by ?2.5 cm-1 (0.3 meV). Below T ? 10 K, effects of spin-lattice relaxation (SLR) are observed and agree with the size of ZFS. According to the combined phosphorescence and TADF, the overall emission decay time is reduced by ?13% as compared to the TADF-only process. The compound may potentially be applied in solution-processed OLEDs, exploiting both the singlet and triplet harvesting mechanisms.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.COA of Formula: C30H24P2, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 13991-08-7, in my other articles.
