Orthogonal Modification of Polymers via Thio–Bromo “Click” Reaction and Supramolecular Chemistry: An Easy Method Toward Head-to-Tail Self-Assembled Supramolecular Polymers.

Chen, S., et al. ACS Macro Letters 2015, 4, 48-52, DOI: http://dx.doi.org/10.1021/mz500747t.

The successful synthesis of the heterotelechelic H-bonding polymer Ba-PnBuA-HW (M_n,NMR = 7700 g/mol, M_n,SEC = 7500 g/mol, PDI = 1.25) was accomplished. Self-assembly in a head-to-tail fashion driven by multiple H-bondings in solution and in the bulk was proven by temperature-dependent ¹H NMR, concentration-dependent DOSY NMR studies, and rheological measurements.
