摘要

In this paper, two conjugated organic small molecules, NITP and NITZ, were designed and synthesized. NITZ is just altered by single atom N-substitution from the NITP thiophene group to the thiazole group in the heterocyclic aryl ring of the skeleton. The morphology and intermolecular stacking style of the fabricated nanofilms were analyzed by atomic force microscopy (AFM), grazing-incidence small-angle X-ray scattering (GISAXS), and X-ray diffraction (XRD). It demonstrates that both molecules prefer highly ordered packing after annealing, and the crystallite orientation is even more superior by N-substitution. As a result, both memory devices exhibit ternary memory performance. This study highlights that the thiazole group also constitutes a good candidate for a π-bridge of organic semiconducting molecules, and it really provides a simple and refined strategy for designing multilevel memory materials by single atom substitution.
