Chromonic nanofibers with the self-assembled Sunset-Yellow(SSY) nanocolumns were fabricated by electrospinning method. Based on the thermal, microscopic and scattering experiments, it was verified that SSY molecules formed a glassy columnar nematic phase in the PVP/SSY nanofiber. When the PVP/SSY nanofiber was annealed above the Tg of PVP, the SSY nanocolumns further self-organized into three-dimensional ordered crystals. The uniaxially oriented nanofiber mats embedding assembled nanocolumns may open the new doors for the practical applications of the spun fibers in optical, electronic and optoelectronic devices.
