| Outline of Research at the Start |
DArP has attracted significant interest as a more atom economical approach to synthesize semiconducting polymers. Typically, semiconducting polymers are synthesized using metal-catalyzed cross-coupling reactions. In DArP, only one of the coupling partners needs to be functionalized. I will investigate CDC polymerizations - they eliminate the need to prefunctionalize the monomers making the synthesis even more atom economical. The research implementation plan above highlights the steps that will be taken to advance CDC polymerizations.

| Outline of Final Research Achievements |
Semiconducting polymers are crucial for organic electronics like OLEDs, OFETs, OPVs, and biomedical sensors. Recent advancements stem from complex polymer syntheses, often costly and unsustainable. Our research focused on improving synthesis through cross-dehydrogenative coupling (CDC) and KCTP.
Key achievements: (1) Monomer Scope Expansion: New monomers, such as furan with tetrafluorobenzene and difluorobenzothiadiazole with thiophene, for CDC polymerization, (2) Donor-Acceptor Monomers: DA-type monomers for living polymerization, enhancing scalability and environmental friendliness, with a 5x rate increase over traditional methods, (3) Kinetics Understanding: Highlighted the impact of monomer structure on reactivity, emphasizing the need for accurate kinetic data for better copolymer design.
These insights are crucial for efficient, cost-effective, and sustainable synthesis processes, enhancing the performance of semiconducting polymers in organic electronics.
