Helical nanostructures with supramolecular chirality formed by the self-assembly of the CP can have circularly polarized light(CPL) detection capability, which has attracted considerable interest in the fields of optoelectronic devices due to their applicability to optical information/communication systems, quantum computing, and invisible sensing systems. The controlled helices with the desired dimension, length, twisted angle, and pitch, which affect the device performance, are greatly demanded to pave the way for the construction of a molecular platform. In this work, we simply induce the supramolecular helicity with preferred handedness into achiral CPs by the simple addition of chiral molecules. It successfully shows the polarization switching in response to the CPL. This chiral transfer strongly dominates the hierarchical self-assembly process of polymers. The amplified chirality through the sergeant-soldier effect was confirmed through circular dichroism spectroscopy measurement
