摘　　要：通过改进传统的酞菁合成方法,得到了一种新的不对称酞菁2-(4-异丙基苯氧基)-9(10),16(17),23(24)-三(4-叔丁基苯氧基)酞菁镍(简称NiPc2),并通过质谱、红外光谱及紫外-可见-近红外光谱对其进行了表征,分析了其可能的形成机理以及循环伏安性质.这种新的不对称酞菁在近红外光区有明显的吸收峰,并且其固体紫外-可见光谱的Q带发生红移,说明形成了J-聚集体.A new asymmetrical nickel phthalocyanine（NiPc2 for short） was synthesized by increasing the temperature of the classical synthetic method,and its structure was characterized by MS,IR and UV-Vis-NIR spectroscopy.Meanwhile,a hypothetical mechanism was suggested and the electrochemical properties was studied by cyclic voltammetry.NiPc2 has strong absorption in near infrared region and prone to be J-aggregates because of the red-shift of the Q band.The NiPc2 has potential application on organic function devices.
