通过亲核取代反应, 在2,2'-联苯二酚氧基环氯磷腈母体N3P3(O2C12H8)2Cl2 (1)和N3P3(O2C12H8)Cl4 (2)上引入2-醛基吡啶与对胺基苯酚形成的席夫碱侧基, 合成了两种新型环磷腈化合物N3P3(O2C12H8)2(p-O-Ph-N＝C-Py)2 (3)和N3P3(O2C12H8)(p-O-Ph-N＝C-Py)4 (4), 这些化合物是一类能形成配合物的多齿配体. 通过元素分析, IR, 1H NMR, 31P NMR和TOFMS确定其结构, 研究了它们的吸收光谱和荧光光谱. H＋和Cu＋离子对其光谱性质的影响研究表明两种化合物的吸收和荧光光谱对H＋和Cu＋离子异常敏感, 因而在作为这些阳离子的荧光探针方面具有应用前景.

A Schiff base group synthesized with 2-aldehydepyridine and 4-aminophenol was introduced into 2,2'-dioxybiphenyl cyclophosphazenes N3P3(O2C12H8)2Cl2 (1) and N3P3(O2C12H8)Cl4 (2) by nucleophilic substitution. Two novel compounds used as multidentate ligands, N3P3(O2C12H8)2(p-O-Ph-N＝C-Py)2 (3) and N3P3(O2C12H8)(p-O-Ph-N＝C-Py)4 (4), were obtained. Their structures were established by elemental analysis, IR, 1H NMR, 31P NMR and TOFMS measurements. The absorption and emission spectra of the two ligands as well as the influences of adding H＋ and Cu＋ ions upon the spectra were investigated. The results indicated that the absorption and emission spectra of the two ligands are sensitive to H＋ and Cu＋ ions, which make them have an applied interest as fluorescent sensors for H＋ and Cu＋ ions.

Key words: cyclophosphazene, Schiff base, spectroscopy, fluorescent sensor
