Abstract

The article represents a translated, revised, and updated Section 6.3 of the monograph by A.S. Burlov, V.G. Vlasenko, D.A. Garnovskiy, A.I. Uraev, E.I. Maltsev, D.A. Lypenko, and A.V. Vannikov, Electroluminescent Organic Light-Emitting Diodes Based on Metal Coordination Compounds, Rostov-on-Don: Yuzhn. Fed. Univ., 2015; ISBN 978-5-9275-1469-4 (see Additional Information). This section is dedicated to reviewing the photoluminescence and electroluminescence properties of metal complexes based on bi- and polydentate ligands of the azomethine type (Schiff bases). Many metal complexes of Schiff bases find wide use as luminescent materials. One of the applications of these compounds is the use as emissive layers or dopants for manufacturing OLED. The photo- and electroluminescence properties of a series of the metal complexes with the ligands based on the derivatives of hydroxybenzaldehyde, 2-(N-tosylamino)benzaldehyde, 1‑phenyl-3-methyl-4-formylpyrazol-5-one, and some others are reviewed. The systematic categorization of these compounds extends beyond their photophysical properties to consider the electroluminescence characteristics observed in OLED devices employing them as the basis. By modifying known azomethine-type ligand systems, one can obtain metal complex compounds with exceptional thermal stability, solubility, and quantum efficiency. These characteristics enable their use as luminescent materials in highly efficient OLED devices.

摘要

本文是 AS Burlov、VG Vlasenko、DA Garnovskiy、AI Uraev、EI Maltsev、DA Lypenko 和 AV Vannikov 翻译、修订和更新的专着第 6.3 节，基于金属配位化合物的电致发光有机发光二极管，顿河畔罗斯托夫：Yuzhn。美联储。大学，2015；ISBN 978-5-9275-1469-4（请参阅其他信息）。本节致力于回顾基于偶氮甲碱型双齿和多齿配体（希夫碱）的金属配合物的光致发光和电致发光性质。许多希夫碱金属配合物广泛用作发光材料。这些化合物的应用之一是用作制造 OLED 的发射层或掺杂剂。一系列以羟基苯甲醛、2-( N-甲苯磺酰氨基)苯甲醛、1-苯基-3-甲基-4-甲酰基吡唑-5-酮等衍生物为配体的金属配合物的光致发光和电致发光性质其他的都经过审查。这些化合物的系统分类超出了它们的光物理性质，还考虑了以它们为基础的 OLED 器件中观察到的电致发光特性。通过修饰已知的偶氮甲碱型配体体系，可以获得具有优异的热稳定性、溶解度和量子效率的金属配合物。这些特性使其能够用作高效 OLED 器件中的发光材料。
