Calix[2]benzo[4]pyrrole m-6 and p-6, each containing two dipyrromethane moieties and two m-phenylene or p-phenylene units, respectively, were readily synthesised from pyrrole, 1,3- and 1,4-bis(1,1'-dimethylhydroxymethyl)benzene, (m-4 and p-4, respectively) and acetone. Macrocycles m-6 and p-6 were tested as receptors for a selection of anions, such as acetate, dihydrogenphosphate and fluoride. The
由吡咯,1,3-和1,4-可以轻松合成分别含有两个二吡咯甲烷部分和两个间亚苯基或对亚苯基单元的杯[2]苯并[4]吡咯m-6和p-6。双(1,1'-二甲基羟甲基)苯(分别为m-4和p-4)和丙酮。测试了大环化合物m-6和p-6作为选择阴离子的受体,例如乙酸根,磷酸二氢根和氟离子。m-6和p-6的X射线结构以及m-6F(-),m-6Cl(-)和m-6CH(3)COO(-)(具有nBu(4)N (+)抗衡离子)也已确定。
