Application: | Niobium(V) chloride can be used:• As a precursor to prepare K2NbF7:Mn4+ red phosphors for white light-emitting diode(LED) devices. • As a Lewis acid to synthesize fluorescein dye derivatives for dye-sensitized solar cells. • As a dopant to enhance the thermoelectric properties of n-type tin selenide. • As a precursor to synthesize Nb2O5 microspheres and TiNb2O7 nanoparticles as high-rate capability and long-cycle-life anode materials for lithium-ion batteries . |
Application: | Used to form mixed chloro-aryloxide compounds, such as [Nb(OC6H3-2,6-i-Pr2)2Cl3]2, which form pyridine or phosphine adducts with a distorted six-coordinate geometry.† |
General description: | Niobium(V) chloride is a yellow crystalline solid with a high melting point. It is widely used in the field of catalysis, semiconductor devices, and batteries. It is a highly specialized Lewis acid in chemical synthesis, activating alkenes for the carbonyl-ene reaction and the Diels-Alder process. |
