Recommanded Product: Copper(I) tetra(acetonitrile) tetrafluoroborate. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: Copper(I) tetra(acetonitrile) tetrafluoroborate, is researched, Molecular C8H12BCuF4N4, CAS is 15418-29-8, about Triarylboron/Triarylamine-Functionalized 2,2′-Bipyridine Ligands and Their Copper(I) Complexes.
We report herein three new either -BMes2 (Mes = mesityl) or -NPh2 group-functionalized 2,2′-bipyridine ligands-4,4′-(p-BMes2-phenyl-CC)2-2,2′-bpy (BB-bpy), 4-(p-BMes2-phenyl-CC)-4′-(p-NPh2-phenyl-CC)-2,2′-bpy (BN-bpy), and 4,4′-(p- NPh2-phenyl-CC)2-2,2′-bpy (NN-bpy)-along with their heteroleptic copper(I) complexes Cu(L)(PPh3)2(BF4) (L = BB-bpy, BN-bpy, and NN-bpy, resp.). The electron-donor and -acceptor units are connected to the bipyridine core via acetylene linkers. The incorporation of acetylene linkers decreases the dihedral angle between the bridging Ph and pyridine rings, resulting in a nearly coplanar geometry of the ligands. All free ligands display temperature-dependent luminescence changes, which may be explained by the twisted intramol. charge-transfer mechanism. Binding with Cu(I) results in significantly red-shifted emission maxima for the heteroleptic complexes Cu(NNbpy)(PPh3)2(BF4) [Cu(NNbpy)] and Cu(BNbpy)(PPh3)2(BF4) [Cu(BNbpy)] relative to those of the free ligands. The electronic and photophys. properties of all compounds were investigated by electrochem., absorption, and emission spectroscopic analyses as well as d. functional theory calculations
