Modern advancement of perylene diimide metal complex: Exposition the coordination modes and applications

Abstract

Perylene diimide (PDI) complexes are highly promising for use in a wide range of rapidly developing fields in the fields of organic electronics, single-compound spectroscopy, supramolecular photochemistry, host-guest chemistry, chemical sensing, gas storage, heterogeneous catalysis, surface-templating, molecular recognition, artificial photosynthetic systems, light-harvesting, solar cells, light emitting diode, field effect transistor, optical sensing, and electron transporting semiconductors in field effect transistor. This is because PDI metal complexes possess high electron mobility, stable radical anions, acting as a building block electron donor, having rich and extended absorption characteristics and possessing highly exothermic electron affinity. They also are electron acceptors and also electron donors, photo stable and can be used in light emitting diodes and photovoltaic cells. The creation of morphologically required functional products presents an intriguing challenge for conventional organic methodology, as the synthetic strategy of PDI complexes relies on coordination noncovalent bonds. Because of this, the mediated metal (transition) synthetic method has received a lot of attention in the past few decades. This has made a variety of supramolecular designs possible, such as three-dimensional cages, linear polymers, molecular cylinders, and planar grids. This review highlights the synthesis and wide range of applications of perylene diimide (PDI) complexes while offering a thorough overview of them. PDI-metal complexes are useful in many scientific fields because of their distinct chemical and electronic properties. Important synthetic routes are highlighted in the review, along with techniques and tactics for intricate fabrication. It investigates design ideas and chemical alterations to customize PDI complexes for various uses. In summary, the present review highlights the diverse properties of PDI-metal complexes and highlights their importance in promoting both scientific research and technological advancement.
