spectroelectrochemistry in DMSO–TBAP. The electrochemical measurements showed that the complexes form ring-based and/or metal-based mixed-valence species, due to the remarkable intramolecular interactions between the two metal phthalocyanine units. The Vulcan XC-72(VC)/Nafion(Nf)/Co2Pc2 modified glassy carbon electrode showed much higher catalytic performance towards oxygen reduction, compared to the VC/Nf/Zn2Pc2
由相应的[4,4'-双(二花生四烯酰基邻苯二甲腈)]合成了新的球形双金属双酞菁(Co 2 Pc 2和Zn 2 Pc 2),该化合物可通过3,3'-亚甲基双(4 -羟基-2 H-色烯-2-酮)和4-硝基邻苯二甲腈。新合成化合物的结构已通过元素分析,UV / Vis,IR和1 H NMR光谱以及MALDI-TOF质谱进行了确认和表征。ITO / Co 2 Pc 2 / C60 / Al和ITO / Zn 2 Pc 2结构的太阳能电池制备了/ C60 / Al。已经研究了有源Pc层的厚度(Pc层的厚度从15到80 nm不等)对太阳能电池参数的影响。在两种结构中均观察到几乎与厚度无关的开路电压。在具有80nm Pc层的ITO / Zn 2 Pc 2 / C60 / Al电池中观察到最大光伏转换效率,短路电流和填充因子分别为0.255%,1mA cm -2和0.38。通过循环伏安法,电势库仑法和原位
