A new family of bridged cyclometallating ligands is reported, which incorporate two terdentate N(wedge)C(wedge)N-coordinating binding sites linked via pyrazine, pyrimidine or pyridazine units. Dinuclear Ir(III) complexes of one ligand have been prepared and crystallographically characterised; they display intense red phosphorescence.
报道了一个新的桥接环金属配体家族,其结合了通过吡嗪,嘧啶或哒嗪单元连接的两个齿状N(楔形)C(楔形)N-配位结合位点。已经制备了一种配体的双核Ir(III)配合物,并进行了结晶学表征。它们显示出强烈的红色磷光。
