Abstract
Cooperative π-π-interactions and H-bonding are frequently exploited in supramolecular polymerization, however, close scrutiny of their mutual interplay has been largely overlooked. Herein, we compare the self-assembly behavior of a series of C2- and C3-symmetrical oligophenyleneethynylenes differing in the amide topology (N- or C-centred). This subtle structural modification brings about drastic changes in their photopysical and supramolecular properties, highlighting the reciprocal impact of H-bonding vs. preorganization on the evolution and final outcome of supramolecular systems.
