Synthesis of Perylene Diimide Derivatives and Its Fluorescent Ability Study

N,N′-di(1-pentylhexyl)-1,7-di(4-t-butylphenoxy)-perylene-3,4:9,10-tetracarboxylic acid diimide was synthesized from perylene-3,4:9,10-tetracarboxylic acid bisanhydride.The compound was characterized by 1H-NMR、MS、UV-Vis absorption spectra and fluorescence spectra.Its fluorescence sensing performance refer to common small organic molecules was studied,and the compoud was found to have good selectivity for aniline.
