Using pyridine-derived cyclometalated ligands and tetraphenylimidodiphosphinate (Htpip) ancillary ligand, three iridium complexes of Ir(ppy)₂tpip (Hppy=2-phenylpyridine), Ir(npy)₂tpip (Hnpy=2-(naphthalene-1-yl)pyridine) and Ir(pnpy)₂tpip (Hpnpy=2-(phenathren-9-yl)pyridine) were synthesized. Their structures were deter-mined by ¹H NMR, MS(MALDI-TOF), and the complex Ir(ppy)₂tpip was also characterized by crystal structure analysis. Extended π conjugation in cyclometalated ligands leads to narrower bandgap resulting in the red shift emission from 516 nm to 600, 633 nm (from green to red). Consequently, when the cyclometalated ligands change from ppy to npy and pnpy, the quantum efficiencies of the complexes are also improved to 0.36, 0.51 and 0.53, respectively. The conjugative effect of the aromatic rings affects the electron density of heterocycle pyridine and thus increases the energy of LUM Oas evidenced by the spectroscopic data and the computational calculation results. The regular patterns between the ligand structure and the emission can be applied for designing novel iridium complexes with various colors.
