Synthesis of a perylene-diimide derivative: Small organic molecule and its characterization towards organic electronics application

In this report, we explain the synthesis scheme and characterization of one derivative of the perylene diimide and its approach towards the organic electronics application, especially, in opto-electronics. The self-assembly and π-π stacking property of this Tryptophan based derivative of perylene diimide has been studied in detail. Along with this, influence of side chain substitution at imide position has been examined. The shape, size and the topography of these small molecules with fiber like structures have been analyzed with the help of FESEM and TEM in different organic solvents. The molecular interaction in the π-π stacking between the side chains was consequently investigated with the help of UV and fluorescence spectrometer to examine the absorption and emission properties. Investigation of the electron transfer ability was done with the help of the DFT calculations and the cyclic voltammetry characterizations. The plane of the molecular stacking was scrutinized with the assistance of XRD analysis.
