Abstract

Square-like metallamacrocyclic palladium(II) complexes [] () were synthesized by reacting aromatic dipyrazole ligands (HL-HL with pyromellitic arylimide-, 1,4,5,8-naphthalenetetracarboxylic arylimide-, and anthracene-based aromatic groups, respectively) with dipalladium corners ((bpy)Pd(NO), (dmbpy)Pd(NO), or (phen)Pd(NO), where bpy = 2,2'-bipyridine, dmbpy = 4,4'-dimethyl-2,2'-bipyridine, and phen = 1,10-phenanthroline) in aqueous solutions via metal-directed self-assembly. Metallamacrocycles were fully characterized by H and C nuclear magnetic resonance spectroscopy and electrospray ionization mass spectrometry, and the square structure of 8NO was further confirmed via single crystal X-ray diffraction. These square-like metallamacrocycles exhibit effective performance for iodine adsorption.

摘要

通过在水溶液中利用金属导向的自组装反应，将芳香族双吡唑配体（HL-HL 分别与均苯四羧酸酰亚胺基、1,4,5,8-萘四羧酸酰亚胺基和蒽基芳香基团反应）与钯的四角体((bpy)Pd(NO)、(dmbpy)Pd(NO)或(phen)Pd(NO)反应，得到了具有类似方形的金属大环钯（II）配合物 [] ()，其中 bpy = 2,2'-联吡啶，dmbpy = 4,4'-二甲基-2,2'-联吡啶，phen = 1,10-菲咯啉）。通过 1H 和 13C 核磁共振波谱和电喷雾质谱对金属大环进行了充分的表征，并通过单晶 X 射线衍射进一步证实了 8NO 的方形结构。这些类似方形的金属大环对碘的吸附具有有效的性能。
