Three new expanded calix[4]pyrroles were synthesized, where the two dialkylldipyrromethane units are linked via C-C double bonds. One of them, calix[2]bispyrrolylethene, colorimetrically senses fluoride ion only, owing to anion-π interaction in polar aprotic solvents.
三种新型的扩展杯[4]吡咯被合成,其中两个二烷基二吡咯甲烷单元通过 C-C 双键连接。其中之一,杯[2]双吡咯乙烯,仅在极性非质子溶剂中通过阴离子-π 相互作用对氟离子进行比色检测。
