We prepared hydrazone ligands derived from 2-hydrazinopyridine, 2-hydrazinoquinoline, benzoylhydrazine, picolinic hydrazide and 2-(alkylthio)benzaldehyde (R = Me, Bu, 4-chlorophenyl)or 2-(diphenylphosphino)benzaldehyde. The NH hydrogen atoms of the coordinated hydrazone ligands on the metal complexes(M = Pd(Il), Pt(11), and Ru(Il)) were easily protonated or deprotonated by the action of acids and bases. The reaction was followed spectrnphotometrically, and the isosbestic points were observed for Pd(II) and Pt(11) complexes. The Ru(II) complexes were oxidized by air after deprotonation to yield Ru complexes. The uncoordinated hydrazone ligands and their Pd(II) and Rua() complexes was not emissive, however, the Pt(11) complexes showed strong emission peaks in the visible region. Reversible large sifts of the emission peaks were observed by the action of acids and bases

我们制备了由2-肼基吡啶、2-肼基喹啉、苯甲酰肼、吡啶甲酰肼和2-(烷硫基)苯甲醛(R = Me、Bu、4-氯苯基)或2-(二苯基膦)苯甲醛衍生的腙配体。金属配合物(M = Pd(II)、Pt(11)和Ru(II))上配位腙配体的NH原子很容易在酸和碱的作用下质子化或去质子化。通过分光光度法跟踪反应，并观察 Pd(II) 和 Pt(11) 配合物的等吸光点。 Ru(II)配合物去质子化后被空气氧化，生成Ru配合物。不配位腙配体及其Pd(II)和Rua()配合物不具有发射性，然而，Pt(11)配合物在可见光区域显示出强发射峰。通过酸和碱的作用观察到发射峰的可逆大筛分
