Using swollen liquid crystals (SLCs) as a soft template, different polyindole nanostructures having different morphology have been synthesized successfully at different temperatures. The SLCs containing indole ring was formed by a quaternary system containing cetyltrimethyl-ammonium bromide (CTAB) or sodium dodecyl sulfate (SDS) as a surfactant, brine, indole:cyclohexane mixture as oil phase and 1-pentanol as co-surfactant. The indole containing mesophases were polymerized using ammonium persulfate as an oxidant and further nanocomposites were extracted from the mesophases. Finally, the extracted and processed samples were characterized using different spectroscopic techniques. The electrochemical properties of polyindole nanostructures were also investigated using cyclic voltammetry.
