Study of Naphthalocyanine Complexes for New Electronic Materials

合成了具有比金属酞菁(MPC)更大的X电子系统的功能性染料--金属萘菁配合物(MNC)，并将其真空蒸发到薄层电极上。研究了这些电极的电致变色、氧还原、光电转化行为，得到了以下结果：(1)MNC的电致变色依赖于中心金属：Co和Fe为正，而Cu和Ni为负。(2)在氧气存在下，没有观察到ConC和FeNc的电致变色。(3)利用结果(2)，可以直观地测量溶解氧浓度的颜色变化。MNCls可用作氧探测器。(4)MNC是氧的四电子还原催化剂。(5)与MPCls相比，UNC电极表现出很小的光电转化能力。然而，在准备好电极后，立即出现了一些照片。-观察电气转换和整流。(6)不同的测量方向，MNC薄层的电阻率相差三个数量级；范德帕斯方法测得的表面方向大于夹层单元方向，反映了吸氧量的不同。(7)MNC只有在消除了氧的情况下才显示出磷光。由此证明，MNc的物理性质受吸氧的影响。

Metal naphthalocyanine complexes(MNc), functional dyes which have larger X-electron systems than -metal phthalocyanines'(MPc), have been synthesized and vacuum evaporated to thin-layered electrodes.Electrochromism, reduction of oxygen, photo-electric conversion behaviors by these electrodes have been examined and the following-results have been obtained.(1)MNc's show electrochromism depending on central metals : Co and Fe are positive but Cu and Ni are negative.(2)Electrochromism of CoNc and FeNc is not observed In the presence of oxygen.(3)Using the result(2), dissolved oxygen concentration can be visually measured as color changes. MNcls can be used as oxygen detectors.(4)MNc's act as four-electron reduction catalysts of oxygen.(5)Contray to MPcls, UNc blectrodes show little photo-electric conversion ability. Inmediately after -the preparation of the electrodes, however, some photo. -electric conversion and rectification are observed. The rectification diminishes vith time.(6)Resistivities of MNc thin layers differ three orders of magnitude depending on the direction measured ; surface direction by van der Pause's method is larger than the sandwich cell direction suggesting the difference of the amount of the absorbed oxygen.(7)MNc's show phosphorescence only in the condition of eliminated oxygen.From these results, the physical properties of MNe's are proved to be influenced by the absorbed oxygen.
