title: Charge-Transfer-Assisted Supramolecular 1 D Nanofibers through a Cholesteric Structure-Directing Agent: Self-Assembly Design for Supramolecular Optoelectronic Materials.
abstract: Self-assembly of pyrene butyric acid (PBA) and 2,4,7-trinitro-9H-fluoren-9-one (TNF) directed by a pyridine-linked cholesterol unit resulted in the formation of a conducting material (1.9472×10(-4)  S Cm(-1) ) due to the formation of 1 D nanofibers. X-ray diffraction, IR, and atomic force microscopic (AFM) techniques were used to establish the mechanism of the self-assembly of the multicomponent gels. Results indicate efficient charge transfer in the 1 D nanofibers, assisted by hydrogen bonding.
