含萘酚直链多胺化合物的合成及对Cu^(2+)的识别

Synthesis of dinaphthol polyamine derivatives and their recognition with Cu^(2+)

以β-萘酚为原料合成了两种含萘酚直链多胺化合物,并用IR、1H NMR、Ms进行了表征。利用紫外分光光度法考察了这两种化合物对金属阳离子的识别性能。实验结果表明,这两种化合物均对Cu2+具有高选择性识别能力,说明在主客体识别中分子尺寸的匹配和化合物中基团的空间合理排布是化合物和Cu2+间能发生相互作用的重要根据。

Two kinds of naphthol containing poly-amino-compounds with different chain length had been synthesized from β-naphthol in this work. They had been identified by IR,1H NMR and MS. Their UV spectra were recorded under different metal cations conditions and showed that two kinds of host molecular had strong selective complexation to Cu2＋. It demonstrated that the molecular size matching and the sterically arrangement of groups of studied compounds with Cu2＋ were very important for the interaction of them.
