A variety of hexacoordinate pincer complexes are described herein having electronic structure advantageous for electronic and/or optoelectronic applications. In some embodiments, the pincer complexes are luminescent, exhibiting fluorescence and/or phosphorescence. Briefly, a hexacoordinate complex comprises a central atom selected from the group consisting of silicon, germanium, and tin, and two pincer ligands bound to the central atom, wherein the hexacoordinate complex is luminescent. In another aspect, a hexacoordinate complex comprises a central atom selected from the group consisting of silicon, germanium and tin, and two pincer ligands bound to the central atom, wherein the difference between the highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) of the hexacoordinate complex is at least 1.5 eV.

Hexacoordinate pincer complexes and applications thereof

In one aspect, light emitting devices are described herein. In some embodiments, a light emitting device described herein comprises an inorganic semiconductor substrate and a layer of quantum dots (QDs) covalently bonded to the inorganic semiconductor substrate. Such a device may further comprise an electrode and an overlayer positioned between the electrode and the layer of QDs. Moreover, the overlayer can be immediately adjacent to and in contact with the layer of QDs. Further, in some cases, the layer of QDs is a close-packed layer of QDs. Additionally, the light emitting device can be a green-emitting light emitting diode (LED) or an amber-emitting LED.
