Synthesis and Characterization of A New Electron Acceptor Perylene Diimide for Further Functionalization

Abstract

Nowadays, novel organic substances are broadly employed in numerous sensing architectures. Clever organic compounds with profound electrochemical and photophysical properties are important for photonic applications. Importantly, electron acceptor properties of perylene derivatives are well known. In the present project, a new perylene bisimide named as N,N′-Bis(2-(4-hydroxyphenyl)ethyl)-3,4,9,10-perylenebis(dicarboximide) (HE-PDI) has been successfully synthesized. The synthesized HE-PDI was characterized by FT-IR and its photophysical properties were studied by UV–vis absorption and emission spectroscopy techniques. HE-PDI has high extinction coefficient and fluorescence quantum yield (Φf = 0.91). The synthesized HE-PDI is completely soluble in the both dipolar aprotic (DMF, DMSO, etc.) and non-polar solvents like (CHL).
