  A novel phosphorescent organometallic iridium complex is provided in which a coordination position of a ligand with respect to a metal can be controlled in synthesis. A novel phosphorescent organometallic iridium complex is provided which can keep high quantum efficiency and can emit phosphorescence in the blue to green wavelength region. A phosphorescent organometallic iridium complex which includes a structure represented by General Formula (G1) and whose ligand is a 4H-1,2,4-triazole compound which has an unsubstituted phenyl group at the 3-position, a substituted or unsubstituted phenyl group at the 4-position, and a phenyl group at the 5-position. In the phenyl group at the 5-position, an alkyl group is bonded to at least one of the ortho-positions, and the other of the ortho-positions, the meta-positions, and the para-position are substituted or unsubstituted.

• Steric Effects on the Regioselectivity in Two-Step Diels–Alder Reactions of 1,2,4,5-Tetrazines with 2-Cyclopropylidene-4,5-dihydro-1,3-dimethyl-imidazolidine

  日期：2000.6

  The regioselectivity of the two-step Diels–Alder reaction of unsymmetrically substituted tetrazines 4 with 2-cyclopropylidene-imidazolidine 6 is investigated. The first reversible step of the cycloaddition affording zwitterions 7 and 8 is controlled by steric effects, which are explained using a simple model. The overall regioselectivity, however, is determined in the second step of the cycloaddition

• Spectral luminescent properties of 2-aryl-5-(2,4,6-trimethylphenyl)-1Н-1,3,4-oxadiazoles

  Reaction of aroylhydrazides with 2,4,6-trimethylbenzoyl chloride in the presence of Et3N afforded N-(mesityl)aroylhydrazides, which through subsequent cyclization at treatment with SOCl2 resulted in 2-aryl-5-(2,4,6-trimethylphenyl)-1De-1,3,4-oxadiazoles. For 2-hydroxyphenyl derivative containing a stable O-H N intramolecular bond a low quantum luminescence yield is observed (phi 0.006-0.038) due to the nonradiative deactivation of the agitated state by ESPIT mechanism.
