Anisotropically oriented chromonic nanofibers embedded self-assembled Sunset-Yellow(SSY) nanocolumns were fabricated by electrospinning process. Regarding on the thermal, microscopic and scattering experiments, it was demonstrated that SSY molecules formed a glassy columnar nematic phase in the PVP/SSY nanofiber. Based on results, it was realized that SSY molecules kept a flat conformation in nano fiber. 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.
