Vibrational strong coupling (VSC) has mostly been used so far to alter chemical reaction rates and product distributions.<sup>1,2</sup> However, very recently it has been shown that it can also affect crystallization and self-assembly processes. Herein, we show the recent results of the modification in the morphology of conducting polymer’s supramolecular assembly <i>via </i>cooperative strong coupling. Under cooperative VSC, we observe amorphous flakes contrary to the fibrous counter assemblies. When the vibrational bands of solvent alone are coupled, self-assembly kinetics is altered. Also, to our surprise, VSC mimics the isotope effect which gives us an insight into the former’s effect on charge distribution and other fundamental properties. Thus we will discuss how VSC could be used as a prospective tool to manipulate supramolecular organizations.<sup>3</sup><br/><br/><br/><b>References</b><br/>1. Nagarajan, K., Thomas, A. & Ebbesen, T.
