Abstract
Three new diketopyrrolopyrrole (DPP) compounds are shown to be colorimetric and ratiometric red fluorescent sensors for fluoride anions with high sensitivity and selectivity. The recognition mechanism is attributed to the intermolecular proton transfer between a hydrogen atom on the lactam N positions of the DPP moiety and the fluoride anion.
摘要
三种新的二酮吡咯并吡咯（DPP）化合物被证明是对氟离子具有高灵敏度和选择性的比色和比率型红色荧光传感器。这种识别机制归因于 DPP 部分中环上酰胺 N 位置上的氢原子与氟离子之间的分子间质子转移。
