报告摘要

Natural biopolymers, such as peptides and nucleic acids, have a precise monomer sequence and stereochemistry along the polymer chain that affords unique biological functions such as molecular recognition (RGD tripeptide), catalysis (enzyme) and data storage (DNA). To reproduce these structurally perfect polymers and understand the mechanism of specific functions through chemical approaches, researchers have proposed using synthetic polymers as an alternative due to their broad chemical diversity and relatively simple manipulation. However, both monomer sequence and stereo-control to mimic the structural precision is still a great challenge. Various approaches to control the monomer sequence or stereoregularity in synthetic polymers have been proposed by researchers from biological and chemical communities. In this talk, we will discuss a recently developed methodology to prepare sequence-controlled and stereospecific oligomers using alternating radical chain growth and sequential photoinduced RAFT single unit monomer insertion (Photo-RAFT SUMI), similar as solid-phase peptide synthesis but producing a full-carbon backbone. This methodology provides a synthesis tool for the assembly of advanced polymer materials for diverse applications.
