Abstract
A self-healing conjugated polymer is disclosed. The self-healing conjugated polymer has hydrogen bonding functional groups introduced into its side chains. Due to this structure, the conjugated polymer is imparted with the ability to recover through self-healing while maintaining its inherent properties (for example, physical and electrical properties). Based on this effective self-healing ability, the conjugated polymer is expected to find application as a biomaterial, a pharmaceutical material, a nonlinear optical material or an organic electronic material.
