Chemical compound
2-Phenylpyridine is an organic compound with the formula C6H5C5H4N (or C11H9N). It is a colourless viscous liquid. The compound and related derivatives have attracted interest as precursors to highly fluorescent metal complexes of possible value as organic light emitting diodes (OLEDs).[1]
The compound is prepared by the reaction of phenyl lithium with pyridine:[2]
- C6H5Li + C5H5N → C6H5-C5H4N + LiH
The reaction of iridium trichloride with 2-phenylpyridine proceeds via cyclometallation to give the chloride-bridged complex:[3][4]
- 4 C6H5-C5H4N + 2 IrCl3(H2O)3 → Ir2Cl2(C6H4-C5H4N)4 + 4 HCl
This complex can be converted to the pictured tris(cyclometallated) derivative tris(2-phenylpyridine)iridium.
