Supramolecular polymerization of electronically complementary linear motifs: anti-cooperativity by attenuated growth

Abstract: The anti-cooperative supramolecular polymerization of compounds 1 and 2, in which the formation of the nuclei is favoured over the growth of the aggregate, is investigated. Despite this anti-cooperativity 1 and 2 can afford co-assembled aggregates.

“…However, potential steric effects of the long dodecyloxy chains, which were not considered in the calculations to reduce computational costs, may also contribute to the observed weak anticooperative behaviour. Interestingly, we observe an increasingly less favorable addition for each monomer upon increasing the alkyl chain length, highlighting the influence of the alkyl chain flexibility (Figure S41 and Table S15) [34] …”

“…Potenzielle sterische Effekte der langen Dodecyloxyketten, die in den Berechnungen nicht berücksichtigt wurden, könnten jedoch auch zu dem beobachteten schwachen antikooperativen Verhalten beitragen. Interessanterweise beobachten wir für jedes Monomer eine zunehmend ungünstigere Addition mit zunehmender Alkylkettenlänge, was den Einfluss der Alkylkettenflexibilität hervorhebt (Abbildung S41 und Tabelle S15) [34] …”

“…[28] Typische Strategien für das anti-kooperative Moleküldesign beruhen auf der Nutzung von Wasserstoffbrückenbindungen, [24,29] oder Dipolmomentaufhebung [22,30] um besonders stabile Dimerkonformationen zu begünstigen, nach denen die Elongation nicht mehr möglich ist. Auf der anderen Seite kann in einigen Fällen die Schwächung des Elongationsschritts durch sterische [25,26,[31][32][33][34] oder coulombisch [35] abstoßende Interaktionen auch ein abgeschwächtes antikooperatives Wachstum begünstigen.…”
