Nat Commun
. 2023 Jun;
14(1):3348.
PMID: 37291098
Supramolecular and covalent polymers share multiple structural effects such as communication mechanisms among monomer repeating units, which are related to their axial helical structure. Herein, a unique multi-helical material combining...

Angew Chem Int Ed Engl
. 2023 May;
62(29):e202303329.
PMID: 37213135
Helix inversion in chiral dynamic helical polymers is usually achieved by conformational changes at the pendant groups induced through external stimuli. Herein, a different mechanism of helix inversion in poly(phenylacetylene)s...

Nat Commun
. 2023 Mar;
14(1):1742.
PMID: 36990975
The helix reversal is a structural motif found in helical polymers in the solid state, but whose existence is elusive in solution. Herein, we have shown how the photochemical electrocyclization...

Diastereomeric multi-chiral pendant groups: Their key role in stimuli-responsive polymeric responses
Rodriguez R, Rivadulla-Cendal E, Quinoa E, Freire F
Chirality
. 2023 Jan;
35(3):172-177.
PMID: 36625726
Chiral information transmission in helical polymers bearing multi-chiral pendant groups is usually determined by the absolute configuration of the first chiral center. The second chiral residue usually has low-to-null influence...

Rodriguez R, Rivadulla-Cendal E, Fernandez-Miguez M, Fernandez B, Maeda K, Quinoa E, et al.
Angew Chem Int Ed Engl
. 2022 Sep;
61(46):e202209953.
PMID: 36121741
In helical polymers, helical sense induction is usually commanded by teleinduction mechanism, where the largest substituent of the chiral residue directly attached to the main chain is the one that...

Nanoscale
. 2022 Sep;
14(36):13066-13072.
PMID: 36069960
A helical copoly(phenylacetylene) that follows a dynamic chiral accord effect has been designed to further synthesize dynamic chiral nanocomposites. Its two pendants are benzamides of (L)-methionine methyl ester [(L)-1, 20%]...

. 2022 Jun;
61(33):e202207623.
PMID: 35731840
Helical polymers such as poly(phenylacetylene)s (PPAs) are interesting materials due to the possibility of tuning their helical scaffold (sense and elongation) once they have been prepared and by the presence...
