Pyrazolone-based ligands are rapidly becoming popular for use in catalysis, in biological applications, in sensors, in functional materials and as pigments for dyes. Many metal complexes with pyrazolone-based ligands have been reported since 80s of the last century, and several of them were found to possess interesting features, such as catalytic activity, anticancer, antioxidant, antifungal and anti-microbial activity, and enhanced NLO, photoluminescence and optical properties with respect to simple pyrazolone-based ligands. Some metal complexes display mesomorphic behavior, others have been investigated as dyes for leather and some also as models for metalloproteins on the basis of their metal environment and spectral features characteristic of important metalloenzymes. Depending on the nature of pyrazolone moieties condensing with primary amine, different classes of pyrazolone-based ligands can be created and used toward metal acceptors. This review provides an overview of this field, with the aim of highlighting both ligand design, synthetic methodology development and relevant applications of the metal complexes.

基于吡唑啉酮的配体正迅速地流行于催化，生物应用，传感器，功能材料中以及用作染料的颜料。自上世纪80年代以来，已经报道了许多具有吡唑啉酮基配体的金属配合物，其中一些具有有趣的功能，例如催化活性，抗癌，抗氧化剂，抗真菌和抗菌活性，以及​​增强的NLO，光致发光。和简单的吡唑啉酮基配体的光学性质。根据金属环境和重要金属酶的光谱特征，一些金属配合物表现出介晶行为，另一些则作为皮革的染料被研究，另一些则作为金属蛋白的模型被研究。根据吡唑啉酮部分与伯胺缩合的性质，可以创建不同类别的基于吡唑啉酮的配体，并将其用于金属受体。这篇综述对这一领域进行了概述，目的是强调配位体设计，合成方法学的发展以及金属配合物的相关应用。
