Two novel calix[4]arene receptors containing ferrocene units in cone (L1) and 1,3-alternate (L2) conformations have been synthesized from 25,27-dihydroxy-26,28-bis[(3-aminopropyl)oxy]calix[4]arene 4 or 25,26,27,28-tetra[(3-aminopropyl)oxy]calix[4]arene 6 and ferrocenecarboxaldehyde via condensation, respectively. Their structures have been characterized by 1H, 13C, APT, COSY NMR, FTIR, HSMR, and UV–vis
两种新型杯[4]芳烃含有二茂铁单元受体锥体(大号1)和1,3-交替(大号2)构象已经从25,27二羟基26,28双合成[(3-氨基丙基)氧基通过缩合反应分别形成] calix [4]芳烃4或25,26,27,28-四[(3-氨基丙基)氧基] calix [4]芳烃6和二茂铁甲醛。它们的结构已通过1 H,13 C,APT,COZY NMR,FTIR,HSMR和UV-vis光谱数据表征。的电化学行为大号1和大号2已在F的存在下进行了研究-,氯- ,溴-,H 2 PO 4 -,CH 3 COO -的阴离子。电化学研究表明,这些受体电化学识别CH 3 COO -,H 2 PO 4 -和Cl - ,阴离子。使用UV-vis研究,证实了在DMSO溶液中对这些阴离子的选择性。
