Barbier single-atom polymerization induced emission as a one-pot approach towards stimuli-responsive luminescent polymers

Abstract

Stimuli-responsive luminescent polymers play important roles in polymer science and are generally designed through polymerization or post-polymerization modification with both stimuli-responsive and luminescent moieties, which involves multistep synthetic procedures. Here,...

Nucleophilic Substitution Polymerization‐Induced Emission of 1,3‐Dicarbonyl Compounds as a Versatile Approach for Aggregation‐Induced Emission Type Non‐Traditional Intrinsic Luminescence†

“…[ 2‐16 ] In comparison with traditional luminescent polymer designed by incorporating luminescent moieties into polymer chain through multiple steps, PIE represents a facile and feasible strategy to realize NTIL through different polymerization methods in one pot. [ 12,16‐20 ]…”

“…For example, polyesterification, polyamidation, coupling polymerizations, ring‐ opening metathesis polymerization, click polymerization, Michael polymerization, multicomponent polymerization, living polymerizations and Barbier polymerization, are based on corresponding esterification, amidation, coupling reactions, olefin metathesis reaction, click reaction, Michael reaction, multicomponent reaction, reversible‐deactivation reactions and Barbier reaction, respectively. [ 12,17‐18,25‐46 ] Further exploration of polymerization methods will expand the monomer, polymer and functionality libraries of polymer chemistry, which will eventually result in the prosperous polymer science with abundant synthetic polymers for a better human life.…”

Radical Polymerization-Induced Nontraditional Intrinsic Luminescence of Triphenylmethyl Azide-Containing Polymers

“…Polymerization-induced emission (PIE), as an emerging strategy, has been proved to design NTIL polymers from nonemissive monomers and attracted considerable attention. − Compared with other strategies for preparation of luminescent polymer through multiple procedures, the advanced PIE strategy combines polymerization and luminescence construction in one pot. − Accordingly, PIE luminogen (PIEgen) can be regarded as the smallest and simplest nonemissive moiety that will become luminescent after being incorporated into polymer chain through polymerization. Therefore, it is very promising to expand the molecular library of PIEgen and investigate the PIE effect.…”

“…Therefore, it is very promising to expand the molecular library of PIEgen and investigate the PIE effect. For examples, through Barbier polymerization of AB, A 2 + B 2 , AB 2 , and A 2 + B type monomers, PIE is proposed, and a series of NTIL polymers have been molecularly designed by PIE strategy with a series of novel PIEgens, including triphenylmethanol and triphenylethanol. ,,,− Through this Barbier polymerization, the luminescent types of these NTIL polymers can be adjusted from aggregation-caused quenching (ACQ) to aggregation-induced emission (AIE). NTIL polymers have also been molecularly designed through different polymerization methods, including but not limited to Michael polyaddition, click polymerization, and multicomponent reaction. ,,− Reversible addition–fragmentation chain transfer (RAFT) polymerization is a versatile polymerization method, which enables polymer chain with narrow molecular weight distribution and has received considerable research attention in the past decades. − Further investigation on the molecular design of novel PIEgens through RAFT PIE is therefore attractive.…”

Barbier polymerization induced emission of cinnamaldehyde: a one-pot Grignard reaction?

“…, Barbier polymerization, resulting in a series of phenylmethanol containing polymers with intriguing nonconjugated luminescence. 6 This Barbier polymerization produces products with intriguing polymerization induced emission (PIE) characteristics, where the obtained nonconjugated luminescence can be easily adjusted from traditional aggregation caused quenching to aggregation induced emission (AIE) by simply adjusting the connection modes of the nonconjugated monomers. We therefore hypothesized whether Barbier polymerization could be used to investigate the difference between the Barbier and Grignard reactions.…”
