【摘要】 由5-氯-2羟基苯甲酮(HCBP)与邻苯二胺(PHEN)的1个胺基缩合得到一苯二胺半体(HCBPPHEN),再将该半体分别与α,ω二(3′羟基4′甲酰苯氧基)取代烷(即1,2二(3′羟基4′甲酰苯氧基)乙烷、1,4二(3′羟基4′甲酰苯氧基)丁烷、1,6二(3′羟基4′甲酰苯氧基)己烷和1,10二(3′羟基4′甲酰苯氧基)癸烷)反应,得到系列新型双二元席夫碱化合物。用元素分析、核磁共振、红外光谱、紫外光谱对其组成和结构进行表征,讨论了烷基链长度和溶剂对双二元席夫碱谱学性质的影响。结果表明,双二元席夫碱随桥连烷基链增长,其分子内两端亚席夫碱单元间采取伸展式构型,两端亚席夫碱单元性质愈与其相应单二元席夫碱的相似。更多还原

【Abstract】 Reaction of 5 chloro 2 hydroxybenzophenone(HCBP) with one amino group of 1,2 diaminobenzene gave a tridentate Schiff base ligand(HCBP PHEN). The free amino group in HCBP PHEN was then reacted with a series of α,ω bis(3′ hydroxy 4′ formylphenyloxy)alkanes to yield the di Schiff base compounds(B n ). The compounds were characterized by elemental analysis, FT IR, 1 H NMR and UV vis spectrophotometry. The spectral properties of the B n have been discussed as a function of alkyl chain length, in comparison with that of the di schiff base monomer(DT).更多还原
