Cross-linking strategies for π-conjugated polymers in organic electronics
-
Audithya Nyayachavadi
Abstract
Organic π-conjugated polymers constitute an important class of semiconducting materials with synthetically tunable optoelectronic and thermomechanical properties. These materials represent an ideal platform for designing emerging electronic and sensing technologies because these materials are also manufacturable at large scale through inexpensive and scalable solution- deposition techniques, thus allowing for the fabrication of new functional technologies at low cost. However, despite these promising features, organic π-conjugated polymer-based technologies suffer from limited lifetime stabilities, and the materials intrinsic solubility in common organic solvents makes advanced fabrication techniques, such as multilayer deposition and nanoscale lithography, challenging. This chapter introduces and reviews emerging strategies that have been utilized by materials scientists for developing cross-linked semiconducting polymers to improve the electronic performance and stability of materials for plastic and soft electronic applications. Throughout, emphasis will be given to designs that utilize supramolecular interactions and chemical motifs incorporated within the side chains and backbone of conjugated polymers that undergo covalent-bond formation, while describing the roles of these interactions and their implications for electronic, processing, and mechanical properties. These highlighted strategies for processing and improving the performance of organic π-conjugated polymers through crosslinking will lead to the development of new materials used in the fabrication of long-lasting and eco-friendly next generation technologies.
