Innovative methodologies have emerged for the precise incorporation of thioester bonds into polymers with controlled sequences. Researchers have developed a versatile and efficient polymerization technique using cyclic thioanhydrides, diacrylates, and diols or diamines as monomers. This method enables the creation of polymers containing ABAC-type repeating units and precisely distributed thioester bonds, offering a wide range of tunable properties.
The synthesis process is notable for its simplicity and efficiency. By employing easily accessible monomers, this metal-free and catalyst-free approach achieves high yields and atom economy. The resulting polymers exhibit diverse characteristics, including adjustable glass-transition temperatures, melting points, degradability, and functionalities derived from thioester groups. Through density functional theory (DFT) calculations, the chemoselectivity of the polymerization mechanism has been elucidated, providing insights into the formation of these complex structures.
This study underscores the potential of sequence-controlled polymers in various applications. The ability to tailor polymer properties through precise structural control opens new avenues in materials science and chemistry. These advancements not only enhance our understanding of polymer synthesis but also pave the way for the development of innovative materials with superior performance. The research highlights the importance of interdisciplinary collaboration and innovation in addressing challenges in polymer chemistry, ultimately contributing to sustainable and advanced material solutions for future technologies.
