By introducing strong directed hydrogen bonds to an amphiphilic polymer, we demonstrate that phase transitions from spherical to cylindrical morphologies in aqueous solutions can significantly be shifted to favor the assembly of supramol. polymer bottlebrushes. In water, a forced self-assembly of polymers into cylindrical structures remains a challenge as the often required hydrophobic shielding induces forces, which tend to minimize the surface area. The herein presented novel benzene trisureas can overcome these limitations due to strong hydrogen bonds and alter the morphol. to cylinders despite an unfavorable packing parameter, which dominated the previously reported trisamide analogs. The systematic variation of composition and architecture revealed that a transition to spherical morphologies still occurs, but the phase-transition boundaries appear to be shifted to tolerate larger hydrophilic polymer chains. The strength of the directing interactions appears to be decisive for the shift, though we addnl. observed that any restrictions of lateral aggregation can diminish the effect of the directing hydrogen bonds. Overall, the straightforward synthesis and versatile design render the presented systems an interesting blueprint for the development of more advanced supramol. polymer bottlebrushes and multifunctional nanostructures. The results came from multiple reactions, including the reaction of N-Boc-1,6-Diaminohexane(cas: 51857-17-1Safety of N-Boc-1,6-Diaminohexane)
N-Boc-1,6-Diaminohexane(cas: 51857-17-1) is used to prepare 1,3-Bis[6-(Boc-amino)hexyl]urea by reacting with carbonyl dichloride in the presence of triethylamine. Further, it is used as a reagent for the introduction of a C6-spacer.Safety of N-Boc-1,6-Diaminohexane
