| Abstract: A new phosphorescent 2-(meta-nitryl-phenyl)-benzothiazolate Iridium(Ⅲ) acetylacetone complex (m-NO2-bt)2Ir(acac) is synthesized by reaction of 2-(meta-nitryl-phenyl)-benzothiazolate with Iridium trichloride anhydrate 2-(meta-nitryl-phenyl)-benzothiazolate, the ligand of the complex, is prepared with meta-nitrobenzoic acid and 2-aminothiophenol as raw materials at the beginning. Then the complex is characterized by 1H NMR, FTIR, Mass spectrometry and Elemental analysis. Solubility, Thermogravitometric analysis, UV-Vis absorption and Photoluminescence of the complex are also investigated. The results indicate that the complex have a better solubility in common organic solvents such as dimethyl-sulfoxide and chloroform. The TGA thermograms show that the complex (m-NO2-bt)2Ir(acac) have a better performance in thermostability and the decomposition temperature almost up to 346 ℃. The absorption spectrum of the complex shows intense high energy transitions 1π-π* from 250 nm to 320 nm, as well as comparatively low energy and broad singlet and triplet metal to ligand charge-transfer (1MLCT and 3MLCT) from 400 nm to 530 nm, and the complex also gives rise to a strong yellow photoluminescence with a peak at 596.5 nm. This Iridium(Ⅲ) complex (m-NO2-bt)2Ir(acac) is a promising organic phosphorescent material for its excellent performance. | |
