Photocontrolled RAFT polymerization: past, present, and future

Chemical Society Reviews, Год журнала: 2023, Номер 52(9), С. 3035 - 3097

Опубликована: Янв. 1, 2023

In this review, we provide a brief history, progress, and applications, discuss the remaining challenges of photocontrolled reversible addition-fragmentation chain transfer (RAFT) polymerization (i.e., photoinduced electron/energy transfer-RAFT (PET-RAFT), photoiniferter, photomediated cationic RAFT polymerization). Among these, visible-light-driven has attracted particular attention in recent years due to its benefits, including low energy consumption safe reaction procedure. Moreover, incorporation visible-light photocatalysis conferred attractive features, such as spatiotemporal control oxygen tolerance; however, clear understanding mechanism not been completely provided. We also present research efforts elucidate mechanisms with aid quantum chemical calculations combined experimental evidence. This review offers an insight into better design systems for desired applications helps realize full potential both academic- industrial-scale applications.

Abstract Synthesis of a polymer composed large discrete number chemically distinct monomers in an absolutely defined aperiodic sequence remains challenge chemistry. The synthesis has largely been limited to oligomers having repeating units due the difficulties associated with step-by-step addition individual achieve high molecular weights. Here we report copolymers α-hydroxy acids, poly(phenyllactic- co -lactic acid) (PcL) built via cross-convergent method from four dyads as constituent units. Our proposed allows scalable sequence-defined PcL minimal coupling steps reagents stoichiometric amounts. Digital information can be stored PcL, which fully retrieved binary code by mass spectrometry sequencing. storage density (bit/Da) is 50% higher than DNA, and capacity also increased adjusting weight (~38 kDa).
