Synthesis of Pyridine-Fused Perylene Imides with an Amidine Moiety for Hydrogen Bonding
摘要:
Pyridine-fused perylene tetracarboxylic acid bisimides (PBIs) were synthesized via Suzuki-Miyaura coupling and acid condensation. The fused PBIs with electron-donating substituents exhibited an intramolecular charge transfer Interaction. One of the N-alkyl substituents was selectively removed with BBr3 to create an amidine guest binding site. A hydrogen bonding Interaction with pentafluorobenzoic acid changed the absorption spectra and enhanced fluorescence.
