Meso-3,5-bis(trifluoromethyl)phenyl picket calix[4]pyrrole 1 displays excellent fluoride anion transport activity across artificial lipid bilayers showing EC₅₀ = 2.15 μM (at 450 s in EYPC vesicle) with high fluoride over chloride ion selectivity. The high fluoride selectivity of 1 was ascribed to the formation of a sandwich type π-anion-π interaction complex.

meso-3,5-双（三氟甲基）苯基尖桩杯[4]吡咯跨膜氟阴离子转运

Meso -3,5-bis(trifluoromethyl)phenyl picket calix[4]pyrrole 1在人工脂质双层中表现出优异的氟阴离子转运活性，显示 EC ₅₀ = 2.15 μM（在 EYPC 囊泡中 450 秒），氟离子对氯离子的选择性高。1的高氟化物选择性归因于夹心型 π-阴离子-π 相互作用复合物的形成。
