Herein, we report a simple fluoride-mediated reaction for the direct mono- and dialkylthio-functionalization of unsubstituted perylenediimides (PDIs) under very mild conditions. The aromatic substitution reaction offers the possibility to introduce primary, secondary and, even, tertiary alkanethiols either on the 1- or on the 1,6-bay positions of unsubstituted PDIs. 1,6-DialkylthioPDIs show that absorption
在这里,我们报告了一个简单的
氟化物介导的反应,可在非常温和的条件下对未取代的ylene二
酰亚胺(PDI)进行直接单和二烷
硫基官能化。芳族取代反应提供了在未取代的PDI的1或1,6-bay位置上引入伯,仲,甚至叔链烷
硫醇的可能性。1,6-二烷基
硫代PDI显示,与未取代的PDI相比,吸收和荧光光谱移至红色,斯托克斯位移约为70-80 nm。
