In this work, the synthesis of new materials formed from metallic phthalocyanines (Pcs) and double potassium salt from 1,8-dihydroxianthraquinone is reported. The newly synthesized materials were characterized by scanning electron microscope (SEM), atomic force microscopy (AFM), infrared (IR) and Ultraviolet-visible (UV-vis) spectroscopy. The powder and thin-film samples of the synthesized materials, deposited by vacuum thermal evaporation, show the same intra-molecular bonds as in the IR spectroscopy studies, which suggests that the thermal evaporation process does not alter these bonds. The effect of temperature on conductivity and electrical conduction mechanism was measured in the thin films (approximately 137 nm thickness). They showed a semiconductor-like behaviour with an optical activation energy arising from indirect transitions of 2.15, 2.13 and 3.6eV for the C(46)H(22)N(8)O(4)KFe, C(46)H(22)N(8)O(4)KPb and C(46)H(22)N(8)O(4)KCo thin films.
在这项工作中，报道了由金属酞菁（Pcs）和1,8 - 二氢蒽醌双钾盐形成的新材料的合成。通过扫描电子显微镜（SEM）、原子力显微镜（AFM）、红外（IR）和紫外 - 可见（UV - vis）光谱对新合成的材料进行了表征。通过真空热蒸发沉积的合成材料的粉末和薄膜样品，显示出与红外光谱研究中相同的分子内键，这表明热蒸发过程不会改变这些键。在薄膜（厚度约为137 nm）中测量了温度对电导率和导电机制的影响。对于C(46)H(22)N(8)O(4)KFe、C(46)H(22)N(8)O(4)KPb和C(46)H(22)N(8)O(4)KCo薄膜，它们表现出类似半导体的行为，其光学激活能源于间接跃迁，分别为2.15、2.13和3.6 eV。
