an important role in tuning the redox potentials along this series. The nitro derivative (compound 2) exhibits several redox couples in its cyclic voltammogram in contrast to the other compounds in this series. The synthesis and characterization of two asymmetrically halogen substituted tetrathiafulvalene (TTF) derivatives 4,4'-bis(4-chlorophenyl)-tetrathiafulvalene ClPhTTF (6) and 4,4'-bis(4-bromo
一系列新的不对称取代的双(二硫代亚乙基)镍(III)化合物[Bu4N] [Ni(Phdt)2](1)(Phdt = 2-Phenyl-1,2-dithiolate)的合成,结构表征和性质,[Bu4N] [Ni(NO2Phdt)2](2)(NO2Phdt = 2-(对硝基苯基)-1,2-二硫代硫酸盐),[Bu4N] [Ni(FPhdt)2](3)(FPhdt = 2- (对氟苯基)-1,2-二硫醇盐),[Bu4N] [Ni(ClPhdt)2](4)(ClPhdt = 2-(对氯苯基)-1,2-二硫醇盐)和[Bu4N] [Ni (BrPhdt)2](5)(BrPhdt = 2-(对溴苯基)-1,2-二硫代硫酸盐)已被描述。所有的配合物1-5在近红外区域均表现出吸收。这些吸收带的移动可通过选择相关二硫代烯部分上的取代基来调节。二硫代烯部分上的取代基也负责其结构多样性。二硫烯部分上的取代基的性质在
