文摘

Supramolecular characteristics studied by the UV–VIS-NIR and DOSY-NMR spectra. Fibrous self-assembly observed by the AFM, SEM and TEM micrographs. Bathochromic shifts in the UV–VIS-NIR spectra indicates fibrous J-type aggregates. DOSY-NMR showed non-linear dependence and results in a self-assembly behavior.
