We report a series of [Cu(P^P)(N^N)][PF6] complexes with P^P = bis(2-(diphenylphosphino)phenyl)ether (POP) or 4,5-bis(diphenylphosphino)-9,9-dimethylxanthene (xantphos) and N^N = 6-methoxy-2,2′-bipyridine (MeObpy), 6-ethoxy-2,2′-bipyridine (EtObpy), 6-phenyloxy-2,2′-bipyridine (PhObpy), 6-methylthio-2,2′-bipyridine (MeSbpy), 6-ethylthio-2,2′-bipyridine (EtSbpy) and 6-phenylthio-2,2′-bipyridine (PhSbpy)
我们报道了一系列[Cu(P ^ P)(N ^ N)] [PF 6 ]配合物,其中P ^ P =双(2-(二苯基膦基)苯基)醚(POP)或4,5-双(二苯基膦基) -9,9-二甲基x吨(xantphos)和N ^ N = 6-甲氧基-2,2'-联吡啶(MeObpy),6-乙氧基-2,2'-联吡啶(EtObpy),6-苯氧基-2,2' -联吡啶(PhObpy),6-甲硫基2,2'-联吡啶(MeSbpy),6-乙硫基2,2'-联吡啶(EtSbpy)和6-苯硫基-2,2'-联吡啶(PhSbpy)。已确定所有十二种化合物的单晶结构,并确定了每个N ^ N和P ^ P配体的螯合模式,以及铜(I)的扭曲的四面体几何形状。对于含黄磷的配合物,不对称的bpy配体排列成6位取代基位于the吨的“碗”上。这些化合物在溶液中的特征是1描述了H,13 C和31 P NMR光谱,及其光物理和电化学性质。它们是黄色发射
