Triarylborane-functionalized polynorbornenes: Direct polymerization and signal amplification in fluoride sensing

Recent Advances in the Synthesis and Applications of Organoborane Polymers

“…The amplified quenching effect was tentatively attributed to through-space exciton migration to lower energy fluoroborate quenching sites. Similar studies were reported by Do and Lee and coworkers for polymers 35, which strongly emit in the violet/UV region with a maximum at 382 nm [55,57].…”

“…3.4) [54]. Alternative approaches include Ziegler-Natta [55,56] and ring-opening metathesis polymerization (ROMP) of borane monomers [57].…”

Organoborane-containing polyacetylene derivatives: synthesis, characterization, and fluoride-sensing properties

“…22,38 Similar results were observed in the cases of triarylboron containing polyolens and polynorbornenes. 25,26 Fig. 1 IR spectra of monomer 1a and polymer 2a.…”

“…For instance, hole-transporting vinyl polymers containing tricoordinate borane moieties were prepared through radical polymerization. 24 Furthermore, Lee and coworkers synthesized luminescent triarylboranefunctionalized polynorbornene 25 and polyolen 26 which display uorescence quenching efficiently in the sensing of uoride ions. However, due to the Lewis acidity of the tricoordinate borane groups which usually deactivate the polymerization reaction, the synthesis of boron-fuctionalized polymers through direct polymerization of the corresponding monomers remains a great challenge.…”

Cyclic Ether Triggers for Polymeric Frustrated Lewis Pair Gels

“…While hydroboration could not be monitored by 11 B NMR spectroscopy due to signal broadening, 33 , 34 complete conversion of (C 6 F 5 ) 2 BH was confirmed by 1 H and 19 F NMR spectra ( Figures S2 and S3 ), with the disappearance of CHD olefin peaks and broadening of the aryl fluorine resonances. A concomitant increase in polymer M n ( P2 ), observed by gel permeation chromatography, correlated to the addition of boron moieties ( Table S1 ).…”
