摘　　要：以2,6-二羟基对甲基苯酚为起始原料,设计并合成了新型阴离子受体2-(2-氨基-4,5-二硝基苯基亚胺)甲基-6-羟甲基-4-甲基苯酚(1),其结构经1H NMR,IR和MS表征。通过UV测试了1对六种阴离子的识别作用。1在DMSO溶液中对F-,AcO-和H2PO4-具有比色识别作用,结合常数Ka大小顺序为F->AcO->H2PO4-,同时UV谱图发生显著变化。而1对Cl-,Br-,I-和HSO4-,颜色和UV-Vis谱图均无明显变化。结果表明,1在DMSO溶液中对F-,AcO-和H2PO4-有识别作用。A novel anion receptor,2-（2-amino-4,5-dinitrophenylimino）methyl-6- hydroxymethyl-4-methylphenol（1）,was designed and synthesized from 2,6- dihydroxyl-p-methylphenol.The structure was characterized by 1H NMR,IR and MS.The recognition properties of 1 for six anions were investigated by UV in DMSO solution.The results showed that 1 can selectively calorimetrically recognize F-,AcO-and H2PO-4,and the sequence of association constants Ka is F-〉AcO-〉H2PO-4.The changes of color and UV absorption were observed in the presence of F-,AcO-,H2PO-4,a neglectable changes appeared after adding Cl-,Br-,I-and HSO-4.
