中文摘要	the synthesis, isomeric studies, and photophysical characterization of a series of multifunctional cyclometalated iridium(iii) complexes containing a fluoro- or methyl-substituted 2[3-(n-plienylcarbazolyl)]pyridine molecular framework are presented. all of the complexes are thermally stable solids and highly efficient electrophosphors. the optical, electrochemical, photo-, and electrophosphorescence traits of these iridium phosphors have been studied in terms of the electronic nature and coordinating site of the aryl or pyridyl ring substituents. the correlation between the functional properties of these phosphors and the results of density functional theory calculations was made. arising from the propensity of the electron-rich carbazolyl group to facilitate hole injection/transport, the presence of such a moiety can increase the highest-occupied molecular orbital levels and improve the charge balance in the resulting complexes relative to the parent phosphor with 2-phenylpyridine ligands. remarkably, the excited-state properties can be manipulated through ligand and substituent effects that allow the tuning of phosphorescence energies from bluish green to deep red.
