Abstract

The self-assembly of pi-conjugated materials into one-dimensional (1-D) nanostructures via intermolecular pi-electron overlap is of particular interest for optoelectronic device miniaturization. There have been a number of pi-conjugated organic semiconductors reported with the ability to self-assemble to produce nanofibers, nanobelts, and nanotubes. However, the majority of these molecules are electron-rich (p-type) and thus the demand for electron-deficient (n-type) semiconductors is high since the availability of useful n-type semiconductors is limited; The design strategy and synthetic routes for novel n-type organic semiconductors based on bisphenazine are reported. The thermal, optical, and electrochemical properties studied by DSC, UV-visible and fluorescence spectroscopy, and cyclic voltammetry (CV) are presented. Electronic properties from theoretical calculations are also compared with the experimental results. The assembling properties, organogelation and 1-D assembly, of these new n-type molecules will be discussed with extensive investigations by scanning electron microscopy (SEM), X-ray diffraction (XRD), and Fourier-Transform infrared (FT-IR) spectroscopy.
