Arg, Lys, His, and Trp were identified that enable controllable peptide–polyphenol assembly via pH/ratio tuning. The resulting materials allow universal protein loading for enzyme cascades, targeted delivery, and stimuli-responsive applications.
The compound [Rh(nbd){κ2P,N-Ph2P(CH2)3NMe2}][BF4] efficiently catalyzes the polymerization of ring-substituted phenylacetylenes to give highly stereoregular megadalton and ultra-high molecular weight polymers with moderate dispersity.
Anilide-PPAs are easily oxidized with Fe3+ ions in a redox process that is accompanied by a colorimetric change in the PPA solution.
Synthetic dynamic helical polymers (supramolecular and covalent) and foldamers share the helix as a structural motif.
A Barbier polymerization method is demonstrated to be a versatile strategy to synthesize polar polyolefin analogues (PPAs), which are further utilized as modifiers to improve the properties of non-polar polyolefins by physically introducing polar groups.
