Study of Naphthalocyanine Complexes for New Electronic Materials

金属酞菁配合物（MNc）是一种比金属酞菁（MPc）具有更大x电子系统的功能染料，已被合成并真空蒸发到薄层电极上。对这些电极的电致变色、氧还原、光电转换行为进行了研究，得到了以下结果：(1)MNc的电致变色取决于中心金属：Co和Fe为正电致变色，Cu和Ni为负电致变色。(2)在氧气的存在下，CoNc和FeNc没有电致变色现象。(3)利用结果(2)，溶解氧浓度可以随着颜色的变化而直观测量。mncl可用作氧检测器。(4)MNc作为氧的四电子还原催化剂。(5)与mpcl相反，UNc电极的光电转换能力很小。然而，在电极制备后，立即产生一些光。-观察电转换和整流。整流随着时间的推移而减弱。(6) MNc薄层的电阻率随测量方向的不同有三个数量级的差异；范德普斯法测得的表面方向大于夹层细胞方向，说明吸氧量的差异。(7)MNc仅在除氧条件下才显示磷光。从这些结果可以看出，锰合金的物理性质受到吸收氧的影响。

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.
