In-Situ GISAXS Study of Supramolecular Nanofibers having Ultrafast Humidity Sensitivity

Abstract Self assembled nanofibers derived from donor-acceptor (D-A) pair of dodecyl methyl viologen (DMV) and potassium salt of coronene tetracarboxylate (CS) is an excellent material for the development of organic electronic devices particularly for ultrafast response to relative humidity (RH).
