Pb(II) complexes of bis(-1,4-phenyl--(4-morpholinedithiocarbamato)) as Pb(II)-S and bis(-diisopropyl--octyldithiocarbamato) as Pb(II)-P were prepared and characterized by optical, structural, morphological, and electrochemical techniques. The scanning electron microscopy analysis of Pb(II)-P and Pb(II)-S complexes consists of cubic crystals. X-ray diffraction and high-resolution transmission electron microscopy spectral studies revealed that the diameter increases in length for alkyl chain groups. This study demonstrates that the cubic shape of Pb(II) complexes can be synthesized from aromatic and aliphatic dithiocarbamate ligands. Photoluminescence analysis of both complexes fell within the blue shift region. The CV curve for Pb(II)-S revealed redox curves and the box-like shape as an indicative of a capacitive behavior, signifying limited catalytic redox activity. The - results for both sensitizers displayed satisfactory conversion efficiency (% η) between 3.77 and 3.96%.
制备了双（-1,4-苯基-（4-吗啉二硫代氨基甲酸盐））作为Pb（II）-S和双（-二异丙基-辛基二硫代氨基甲酸盐）作为Pb（II）-P的Pb（II）配合物，并通过光学、结构、形态和电化学技术对其进行了表征。Pb（II）-P和Pb（II）-S配合物的扫描电子显微镜分析由立方晶体组成。X射线衍射和高分辨率透射电子显微镜光谱研究表明，烷基链基团的直径在长度上增加。该研究表明，Pb（II）配合物的立方形状可以由芳族和脂肪族二硫代氨基甲酸盐配体合成。两种配合物的光致发光分析都落在蓝移区域内。Pb（II）-S的循环伏安曲线显示出氧化还原曲线和盒状形状，表明具有电容行为，意味着催化氧化还原活性有限。两种敏化剂的结果显示出令人满意的转换效率（%η），在3.77%至3.96%之间。
