Herein, we report two novel derivatives of hexabenzoperylene (HBP) that are functionalized with ester groups. Methyl acetate functionalized HBP (1) in single crystals self-assembles into a supramolecular nanosheet, which has a two-dimensional π-stack of HBP sandwiched between two layers of ester groups. With the same self-assembly motif, active ester-functionalized HBP (2) in field effect transistors has enabled differentiation of tertiary amines from primary and secondary amines, in agreement with the fact that active ester reacts with primary and secondary amines but not with tertiary amines to form amides.
在此，我们报道了两种用酯基官能化的六苯并蒄（HBP）新型衍生物。单晶中的乙酸甲酯官能化HBP（1）自组装成超分子纳米片，其具有夹在两层酯基之间的二维HBP π堆积。基于相同的自组装模式，场效应晶体管中的活性酯官能化HBP（2）能够区分叔胺与伯胺和仲胺，这与活性酯与伯胺和仲胺反应但不与叔胺反应形成酰胺这一事实相符。
