利用氧化还原反应合成了含膦配体双二苯基膦甲烷(dppm)及其铜(I)配合物[Cu2(dppm)2(NO3)2],[Cu(dppm)Br]3,[Cu2(dppm)2(SO4)],[Cu(dppm)(HCOO)]2和[Cu(dppm)(CH3COO)]2;并经紫外、红外、拉曼、荧光光谱等物理化学方法表征了[Cu(dppm)Br]3和[Cu2(dppm)2(NO3)2]的结构与性质.结果表明:1)含dppm的铜配合物红外光谱具有dppm的特征吸收.2)该类配合物的紫外吸收是由配体dppm的吸收造成的,而与配合物的形成无关.3)利用拉曼光谱测出[Cu(dppm)Br]3中存在Cu-Cu金属键,而[Cu2(dppm)2(NO3)2]没有.4)该类配合物具有重要的荧光性质,其中[Cu2(dppm)2(NO3)2]和[Cu(dppm)Br]3的最大荧光波长分别为470nm和510nm.
The phosphine ligands such as bisdiphenylphosphine methane (dppm) and its copper complexes [Cu2 (dppm) 2 (NO3) 2], [Cu (dppm) 2 (SO4)], [Cu (dppm) (HCOO)] 2 and [Cu (dppm) (CH3COO)] 2 were synthesized and characterized by means of physicochemical methods such as UV, IR, Raman and fluorescence spectroscopy. (dppm) Br] 3 and [Cu2 (dppm) 2 (NO3) 2] were studied.The results showed that: 1) The dppm-containing copper complex had a characteristic absorption of dppm in the infrared spectrum.2) The UV- Absorption is due to the absorption of the ligand dppm, irrespective of the complex formation.3) The presence of Cu-Cu metal bonds in [Cu (dppm) Br] 3 by Raman spectroscopy and the presence of [Cu2 (NO3) 2] .4) The complexes have important fluorescent properties, and the maximum fluorescence wavelength of [Cu2 (dppm) 2 (NO3) 2] and [Cu (dppm) Br] 3 are 470nm and 510nm, respectively.
