Abstract
A novel ion-bonded discotic complex was prepared from 2,3,6,7,10,11-hexakis( N, N-dimethylaminopropylaminocarbonylmethoxy)triphenylene (HDTP) and 4′-dodecyloxybiphenyl-4-carboxylic acid (DBC) by ionic self-assembly (ISA) route and characterized by Fourier transform infrared (FTIR) spectrum. We found that the complex can self-assemble into stable gels in aromatic hydrocarbons. Nanofibers with diameters of 50–130 nm were observed in the gels by transmission electron micrograph (TEM). The FTIR data in conjunction with UV–vis and fluorescence spectra suggested that the aggregation of the complex into elongated fibers in solution was induced by a directional extended network of hydrogen bonds and π–π interactions. Based on the experiment analysis, we proposed a tentative model of the self-assembly of this two-component gel-phase material.
