Abstract
Light-emitting electrochemical cells (LECs) are attracting significant attention due to their simple design, low production costs, and ability to operate on flexible substrates. As a result, they are increasingly considered a highly attractive alternative to organic light-emitting diodes (OLEDs). The emissive layer is a key element determining the efficiency of LECs. Therefore, considerable attention is currently being paid to finding chemical compounds that could be used as efficient and stable light emitters. Ionic transition metal complexes (iTMCs) are a prime example of such materials. In recent years, iridium and ruthenium complexes containing ligands based on 1H-imidazo[4,5-f][1,10]phenanthroline derivatives have attracted particular interest in LECs. Therefore, this paper discusses in detail the physicochemical properties and application potential of iridium and ruthenium complexes containing these ligands in LECs.
期刊介绍:
Materials (ISSN 1996-1944) is an open access journal of related scientific research and technology development. It publishes reviews, regular research papers (articles) and short communications. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. Therefore, there is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Materials provides a forum for publishing papers which advance the in-depth understanding of the relationship between the structure, the properties or the functions of all kinds of materials. Chemical syntheses, chemical structures and mechanical, chemical, electronic, magnetic and optical properties and various applications will be considered.
