两个由1,1′-环己烷二乙酸构筑的镉的配合物的合成、晶体结构和荧光性质(英文)

Syntheses, Structures and Fluorescence of Two Cd(II) Complexes Constructed from 1,1′-Cyclohexanediacetic Acid

通过邻羧苯乙酸、1,10-邻菲啰啉及硝酸镉的溶剂热反应合成了2个配合物:[Cd(phen)(chdc)]n(1)和[Cd(phen)(chdc)(H2O)]n(2)。X-射线单晶衍射显示:1是梯状双链结构;2是单链结构,单链再通过氢键连接成双链。虽然1和2的组分相似,但它们在固态条件下的荧光发射却大不一样,可能在光化学方面有潜在的应用。

Two complexes of 1,1′-cyclohexanediacetic acid （H2chdc）, [Cd（phen）（chdc）]n （1） and [Cd（phen）（chdc） （H2O）]n （2）, have been synthesized through solvothermal reactions of H2chdcc, 1,10-phenanthroline （phen） and cadmium nitrate. The crystal structures of two complexes reveal that 1 has a ladder-like double-chain structure, while 2 consists of linear single chains, which are further linked to form double-chains through hydrogen bonding. Although consisted of similar components, 1 and 2 exhibit different intense fluorescence emission in solid state, which may have promising application in photophysical chemistry.
