“…This strategy was extended later to the macromolecular systems wherein specific complementary D-A binding motifs could help in determining the sequence of high-molecularweight polymers [126] in the short as well as long range. [127,128] This group further utilized the pyrene-NDI alternate stacking interaction to demonstrate supramolecular crosslinking of a folded polymer. The system consists of a polyamide backbone with pyrene groups at both ends while the folding of the other polymer is achieved by intrachain p-stacking interactions between the NDI units.…”

We have collated various supramolecular designs that utilize organic donor-acceptor CT complexation to generate noncovalently co-assembled structures including fibrillar gels, micelles, vesicles, nanotubes, foldamers, conformationally restricted macromolecules, and liquid crystalline phases. Possibly inspired by nature, chemists have extensively used hydrogen bonding as a tool for supramolecular assemblies of a diverse range of abiotic building blocks. As a structural motif, CT complexes can be compared to hydrogen-bonded complexes in its directional nature and complementarities. Additional advantages of CT interactions include wider solvent tolerance and easy spectroscopic probing. Nevertheless the major limitation is their low association constant. This article shows different strategies have evolved over the years to overcome this drawback by reinforcing the CT interactions with auxiliary noncovalent forces without hampering the alternate stacking mode. Emerging reports on promising CT complexes in organic electronics are intimately related to various supramolecular designs that one can postulate based on donor-acceptor CT interactions.

“…Resonances associated with the perylenyl end-group are also seen to shift upfield and become broader in appearance. The complex pattern observed for the bound naphthyl and perylenyl proton resonances in the polymer blend arises from the range of different binding sequences [56,57] within the random co-polymer backbone (i.e. dimer, trimer, etc.)…”

a b s t r a c tA two-component, supramolecular polymer blend has been designed using a novel p-electron rich bisperylene-terminated polyether. This polymer is able to self-assemble through electronically complementary pep stacking interactions with a p-electron-deficient chain-folding polydiimide to afford thermally healable polymer blends. Model compounds were developed to assess the suitability of the deep green complexes formed between perylene residues and chain-folding bis-diimides for use in polymer blends. The polymer blends thus synthesised were elastomeric in nature and demonstrated healable properties as demonstrated by scanning electron microscopy. Healing was observed to occur rapidly at ca. 75 C, and excellent healing efficiencies were found by tensometric and rheometric analyses. These tuneable, stimuli-responsive, supramolecular polymer blends are compared to related healable blends featuring pyrene-terminated oligomers.
