摘　　要：在1,10-菲咯啉的5,6-位引入烷氧基后,分子的反应活性明显提升,同时获得的三苯胺基(TPA)衍生物的溶解性也明显提高。晶体结构分析表明:烷氧基团是以六元环形式的乙撑二氧结构接入1,10-菲咯啉环的5,6-位。化合物TPA1和TPA2均对Ag+表现出选择性识别作用。其中,TPA1与Ag+作用后虽然荧光减弱不明显,但其发射波长明显红移(47 nm)。而TPA2和Ag+作用后,415和542 nm处荧光发射峰同时淬灭。化合物TPA3虽然也能与Ag+发生相互作用使荧光减弱,但是其荧光减弱幅度不大,很容易受到其它杂离子干扰影响,不适用于离子识别研究。The introduction of alkoxyl groups to 5,6-positions of 1,10-phenanthroline can not only lead to the enhancement of the reaction activity, but also increase the solubility of the targeted compounds. Crystal structure analyses reveal that the two alkoxyl groups at 5,6-positions of 1,10-phenanthroline adopt double six-membered ethylenedioxy cyclic conformation. Both TPA1 and TPA2 show selective recognition toward the silver ion. No obvious fluorescence quenching is found after the treatment of TPA1 and Ag＋, in which a red shift of 47 nm in the fluorescence emission spectrum is observed. On the other hand, the two emission peaks at 415 and 542 nm in the fluorescence emission spectra are quenched when TPA2 is reacted with Ag＋. However, the fluorescence quenching effect for Ag＋is not obvious in the case of TPA3, which makes it not a good candidate for the metalion recognition.
