Thieno[2,3-d]pyridazine cyclometalated iridium complex and preparation method thereof

The invention discloses a thieno[2,3-d]pyridazine cyclometalated iridium complex and a preparation method thereof, belonging to the field of organic photoelectric materials. The thieno[2,3-d]pyridazine cyclometalated iridium complex provided by the invention overcomes the problems that an existing cyclometalated iridium complex is very sensitive to oxygen, and the quantum efficiency of the existing pyridazine iridium complex is not high. The preparation method comprises the following steps: synthesizing a monochloro-substituted thieno[2,3-d]pyridazine intermediate through a four-step reaction;mixing the monochloro-substituted thieno[2,3-d]pyridazine intermediate with substituted phenol, substituted thiophenol, substituted aniline or substituted carbazole active hydrogen-containing compounds dissolved in an organic solvent, adding alkali, and carrying out a reaction to generate thieno[2,3-d]pyridazine ligand; and mixing the obtained thieno[2,3-d]pyridazine ligand with iridium trichloride and a solvent, and carrying out a reaction for a period of time to obtain the thieno[2,3-d]pyridazine cyclometalated iridium complex.

Trifluoroacetic acid catalyzed dibenzodiazocine synthesis: Optimization and mechanism study

Dibenzo[b,f][1,5]diazocines, a class of potential building blocks for novel electrochemical actuators, were synthesized via a novel, efficient acid-catalyzed reaction of 2-acylbenzoisocyanate at room temperature. Real-time NMR analysis and the captured intermediate showed the mechanism was an unprecedented cyclization of the isocyanate with the neighboring acyl group, followed by the dimerization.
