The electronic structure in the ground and lowest triplet excited states, the frontier molecular orbitals, the absorption spectra, and phosphorescence properties of five iridium(III) complexes bearing fluorine substituted 2,3 ' bipyridine and bromine substituted pyridinyltetrazolate ligands have been investigated to explore blue phosphorescent materials. Complexes 1-5 have different transitions responsible for the phosphorescence wavelength. The emission wavelengths of 2, 4 and 5 have an obvious redshift in comparison with 1, indicating that changing the main ligand can effectively adjust the phosphorescence properties. Complex 3 has the best balance of charge transport among these complexes.
