摘要： 合成了一种N-烷基链单取代DPP衍生物2-辛基-3,6-二(4-(9,9-二辛基芴-2-)苯基)吡咯并吡咯-1,4-二酮（DPFL），它可作为新颖有效且具有可选择性的比色型氟离子荧光传感器，与DPFL在正己烷和乙腈以及水与四氢呋喃（THF）混合（体积比1∶1）溶液中相比，它在THF中有更高的灵敏性，氟离子加入后由于去质子化作用其荧光光色发生从黄色到红色的明显变化。

Abstract: We have synthesized one N-monoalkylated diketopyrrolopyrrole derivative,2-octyl- 3,6-bis(4-(9,9-dioctyl-9H-fluoren-2-yl)phenyl)pyrrolo［3,4-c］pyrrole-1,4(2H,5H)-dione(DPFL),which is a novel and efficient colorimetric and fluorescent fluoride sensor with high selectivity.Compare to DPFL in hexane, acetonitrile and dispersion of water and THF(volume ratio of 1∶1), it exhibits the better sensitive in THF.Due to deprotonation the addition of fluoride results in vivid yellow-to-red emission color change.
Key words: fluoride anion; diketopyrrolopyrrole; fluorescent sensor; colorimetric sensor
