报道了十种含有 2-羟基苯酮配体的铜 (II) 配合物的合成、鉴定和电化学行为。铜 (II) 配合物的还原遵循与游离配体还原相同的趋势。铜 (II) 配合物的第一次还原是基于金属的,并且发生在比游离配体还原高 1 V 以上的电位下。在实验值(从实验还原电位获得)和计算化学计算的铜 (II) 配合物的能量之间获得了线性关系。这些线性关系证实了配体和铜之间的良好沟通,可用于预测类似铜 (II) 配合物的还原电位。
The present investigation reports the novel synthesis of copper nanocrystals using thermal reduction, and their physicochemical characterization. The copper nanocrystal powder has been prepared using [bis(2-hydroxyacetophenato)copper(II)] as a precursor. The effect of oleylamine and triphenylphosphine on the particle morphology has been investigated. Transmission electron microscopy (TEM) analysis has demonstrated that the copper nanocrystals have an average diameter of about 3 nm. The as-prepared copper nanocrystals were characterized by XRD, SEM, TEM, EDX. UV-Vis and FTIR. (C) 2008 Elsevier Ltd. All rights reserved.
