<p>We report <a>the synthesis and characterization
of self-assembled</a> structures formed by4-Choro-2(3H)-benzothiazolone (<b>VK</b>)
to panchromatic fibers and its application as cell imaging tool. The
aggregation properties ofthe synthesized compounds have been studied
extensively under different solvent and concentrationand theirmorphologies
examined at supramolecular level was observed by microscopic techniques like
optical microscopy, fluorescence microscopy, and atomic force microscopy(AFM). Interestingly,
the self-assembled structures formed by <b>VK</b>reveal panchromatic emission properties
andshow blue, green and red fluorescence under different excitation filters.
The intensity of the fluorescence observed was blue>green>red and the dye
interestingly do not show any fluorescence quenching, on the other hand reveal
photoactive properties under green channel. The mechanisms of formation of the
self-assemblies were studied through different techniques like concentration
dependent NMR and,UV visible spectroscopy and fluorescencemicroscopic studies.Finally,
the utility of <b>VK</b> for cell imaging applications is demonstrated and it
can be noted that <b>VK</b> can be efficientlyup taken by mammalian cells and
the stained cells reveal panchromatic emission under blue, green and red
channel.<b></b></p>
