Dithocarbamate metal complexes have been used to prepare nanoparticles and nanowires of a variety of semiconducting metals including CdS, ZnS, PbS, and EuS. The two new cadmium (II) L-Proline Dithiocarbamate and zinc (II) L-proline dithiocarbamate complexes have been synthesized. Both of the metal complexes are able to produce semiconductor sulphides, nanoparticles which are applicable in the electronic industries. The amino acid L-proline has the unique property, it is the only DNA determined amino acid which has a secondary five membered cyclic amino group alpha to the carbonyl group in the biosystem. Metal dithiocarbamate which is derived from L-proline is able to produce the corresponding metal sulphides as nanoparticles and nanowire. This is very much applicable in Thin Film Technology. Besides, the Zinc complex is used as a drug in increasing the immune system of the body against bacteria and viruses. Zinc dithiocarbamate derived from alpha aminoacid is biocompatible so that it can be used as pharmaceutical products. The two complexes exhibit the important NCS2 peak from 202.73-215 in 13C NMR, attributing to the presence of the dithiocarbamate ligand. A resonance signal around δ 4.92 is due to COOH-proton in 1H NMR. The complexes also shows the important IR frequencies, ν(CN), ν(CS) and ν(CO) in the ranges 1443-1430 cm-1, 954-945 cm-1 , and 1720-1712 cm-1 , respectively. LMCT transitions have been observed at λ 214 nm for the Cd complex. Based on the thermo gram the complexes are stable up to 200°C, and fast decomposed to produce M(SCN)2 at 400C and finally MS(M= Cd), as residue at 600°C by slow steps. From FTIR, 1H, 13C NMR, only dithiocarbamate sulphurs are coordinated to metal and not the carboxylate oxygen in the two complexes.

α-氨基酸 L-脯氨酸衍生的二硫代氨基甲酸镉锌配合物的合成与表征

双氨基甲酸酯金属配合物已被用于制备包括 CdS、ZnS、PbS 和 EuS 在内的多种半导体金属的纳米颗粒和纳米线。已经合成了两种新的镉 (II) L-脯氨酸二硫代氨基甲酸酯和锌 (II) L-脯氨酸二硫代氨基甲酸酯配合物。这两种金属配合物都能够生产适用于电子工业的半导体硫化物、纳米颗粒。氨基酸L-脯氨酸具有独特的性质，它是生物系统中唯一在羰基的α位具有二级五元环状氨基的DNA确定氨基酸。衍生自 L-脯氨酸的金属二硫代氨基甲酸盐能够产生相应的金属硫化物作为纳米颗粒和纳米线。这在薄膜技术中非常适用。除了，锌复合物被用作增强人体免疫系统对抗细菌和病毒的药物。源自α氨基酸的二硫代氨基甲酸锌具有生物相容性，因此可用作医药产品。这两种配合物在 13C NMR 中表现出 202.73-215 的重要 NCS2 峰，归因于二硫代氨基甲酸酯配体的存在。δ 4.92 附近的共振信号是由 1H NMR 中的 COOH-质子引起的。这些复合物还分别显示了 1443-1430 cm-1、954-945 cm-1 和 1720-1712 cm-1 范围内的重要 IR 频率 ν(CN)、ν(CS) 和 ν(CO)。已在 λ 214 nm 处观察到 Cd 配合物的 LMCT 跃迁。根据热分析图，配合物在 200°C 下是稳定的，并在 400°C 下快速分解生成 M(SCN)2，最后在 600°C 缓慢分解生成 MS(M= Cd)，作为残留物。从 FTIR、1H、13C NMR、
