The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.166330-10-5, Name is (Oxybis(2,1-phenylene))bis(diphenylphosphine), molecular formula is C36H28OP2.

A series of mononuclear Cu(I)-halide complexes, [CuX(PPh3)2(L)] (X=Cl-, Br-, I-; PPh3Combining double low linetriphenylphosphine; LCombining double low linepyridine (py), isoquinoline (iq), 1,6-naphthyridine (nap)), were synthesized. The emission color of [CuX(PPh3)2(L)] varies from blue to red by changing the L ligands and the halide ions, and all the complexes exhibit high emission quantum yields (0.16-0.99) in the crystals. The emission studies revealed that the emissive states of [CuX(PPh3)2(L)] differ depending on the L ligand. Complexes [CuX(PPh3)2(py)] and [CuX(PPh3)2(nap)] mainly emit from the singlet metal-to-ligand charge transfer mixed with the halide-to-ligand charge transfer (1(M+X)LCT) state at room temperature. In contrast, emissions from [CuX(PPh3)2(iq)] at room temperature originate from both 3(M+X)LCT and 3 pi pi?states. These results indicate that N-heteroaromatic ligands play an important role in the emission properties of mononuclear Cu(I)-halide complexes.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: (Oxybis(2,1-phenylene))bis(diphenylphosphine), you can also check out more blogs about166330-10-5
