An, Lianying published the artcileSyntheses of a green organic phosphorescence materials and studies on their photoluminescent properties, Recommanded Product: 1,2-Diphenyl-1H-benzo[d]imidazole, the publication is Advanced Materials Research (Durnten-Zurich, Switzerland) (2012), 455-456(Pt. 2), 880-883, database is CAplus.
By using the N-phenyl-o-nitroaniline and benzoyl chloride as initial raw materials, a green light-emitting material (pbi)2Ir(acac)2 (pbiH = 1,2-diphenylbenzimidazole) was produced via a new designed synthesis plan. The structure of the complex was characterized by IR, MS, and DTA. The optical Luminescence Properties of the complex was studied by fluorescence spectrometry anal. The m.p. of the product is 343° which showed that it had thermal stability. The fluorescence spectrometry anal. exptl. results show that the excitation and emission peaks of the organic Ir(III) complex were, resp., 470.6 nm and 526.21 nm which showed that it belongs to green high-brightness light-emitting materials. The oxidation of the intermediate products exposed in air which could cause the quality of product instability was avoided in the new, improved synthesis plan.
