| 中文摘要 | by tuning the substitution position of a thiazolyl group on the naphthalene system (a or beta site), the distinctive electronic structures associated with these functional ligands have a substantial influence on both the photophysical behavior and electroluminescent (el) performance of the resulting linkage isomers for two series of iriii and ptii phosphorescent emitters. the photoluminescence wavelength can be redshifted by ca. 23 nm for the linkage isomers upon replacing the beta-substituted thiazolyl-based ligand with its a-substituted counterpart in the homoleptic series of iriii phosphors. furthermore, the bathochromic effect can be as much as ca. 42 nm for the heteroleptic iriii phosphors and ca. 59 nm for the ptii compounds. similarly, metallophosphors that bear beta-substituted ligands exhibit a different el performance with respect to that of their linkage isomers with a-substituted ligands. the best el results associated with the triplet emitters chelated with beta-substituted ligands show a maximum brightness (lmax) of 22563 cd?m2, an external quantum efficiency (?ext) of 12.88?%, a luminance efficiency (?l) of 30.84 cd?a1, and a power efficiency (?p) of 26.17 lm?w1, whereas the el performance of their a-counterparts was characterized by a peak lmax of 8653 cd?m2, ?ext of 6.18?%, ?l of 8.55 cd?a1, and ?p of 6.54 lm?w1. owing to its unique electronic structure, the thiazolyl group is a good alternative to the pyridyl moiety to improve the el performance of the metallophosphor. we have also demonstrated a simple and useful route to tune the functional properties of cyclometalated triplet emitters for el applications. |
