Luminescent manganese(II) complexes offer tunable colors and high stability for applications like LEDs and radiation detection. Their emission properties are linked to crystal structure and the manganese(II) ion environment.
Area of Science:
- Materials Science
- Inorganic Chemistry
- Solid-State Physics
Background:
- Luminescent manganese(II) complexes exhibit desirable properties including color tunability, high photoluminescence quantum yields (PLQYs), large Stokes shifts, and thermal stability.
- The emission color of Mn(II) complexes can be tuned across orange, green, and red wavelengths, influenced by the coordination environment of the Mn2+ ion.
Purpose of the Study:
- To establish a connection between the luminescent properties of Mn(II) complexes and their corresponding crystal structures and Mn2+ environments.
- To review recent advancements in the application of luminescent Mn(II) complexes in light-emitting diodes (LEDs) and radiation detection.
- To identify current challenges and future research directions for luminescent Mn(II) complexes.
Main Methods:
- Crystallographic analysis to determine the local environment of Mn2+ ions.

Properties of Transition Metals
Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...
Properties of Organometallic Compounds
Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can...
Alkyl Halides
Alkyl halides are halogen-substituted alkanes wherein one or more hydrogen atoms of an alkane is replaced by a halogen atom such as fluorine, chlorine, bromine, or iodine. The carbon atom in an alkyl halide is bonded to the halogen atom, which is sp3-hybridized and exhibits a tetrahedral shape.
Unlike alkyl halides, compounds in which a halogen atom is bonded to an sp2 -hybridized carbon atom of a carbon-carbon double bond (C=C) are called vinyl halides. Whereas aryl...
