Abstract
Nanomaterials assembled from small functional organic molecules have intriguing application potentials in the field of optoelectronic devices. In this work, we report a facile method for the fabrication of nanowires with different sizes from the nonlinear optical organic molecule 2-(4′-aminophenyl)-6-nitro-1,3-diazaazulene (APNA) with typical D-π-A structure. In addition, the synthetic route of APNA was greatly simplified with satisfactory yield. The average diameters of APNA nanowires, 50, 70 and 120nm, could be controlled through the amounts of APNA in the reprecipitation process, which was characterized by SEM. Moreover, the absorption properties of the nanowires were also investigated and compared. This work may facilitate the researches and applications of azulene and its derivatives.
