Nature-Inspired Conjugated Organic Polymer: Self-Healing and Stretchability Via Ureidopyrimidine Functionalization

In the realm of organic electronics, the development of self-healing materials has gained paramount importance, finding diverse applications including electronic skin, sensors, solar cells, supercapacitors, coatings, and adhesives. This study presents a novel class of self-healing polymers derived from conjugated monomers (DPP) featuring Ureidopyrimidine sidechain functionality. These sidechains exhibit a remarkable capacity for intramolecular hydrogen bond formation, imparting self-healing properties, flexibility, and stretchability to solid-state polymeric films. The synergistic combination of self-healing attributes with the inherent advantages of conjugated polymers holds substantial promise for various applications. Ureidopyrimidinone, characterized by its reversible bonding properties and compatibility with conjugated polymers, emerges as a particularly auspicious self-healing group. This research delves deep into the realm of material chemistry and engineering, embarking on a journey to redefine the boundaries of polymer properties. Through meticulous manipulation of these materials, facilitated by Ureidopyrimidinone functionalities, we are dedicated to pushing the limits of what is attainable. Our ultimate goal is to engineer flawless polymers that set new standards for performance in organic field-effect transistors (OFETs). This ambitious endeavor represents a pioneering effort at the intersection of material chemistry and engineering, where we challenge convention and strive to create the perfect materials for the next generation of electronic devices, with a specific emphasis on their utility in electronic skin.
