Key words

double helical polymers - hetero-strand - salt bridge

Significance

Reported is the first synthetic het­ero-strand double helical polymer. Two complementary homopolymers 1 and 2 assembled into a perfect double helix via an interstrand amidinium-carboxylate salt bridge in a polar solvent such as THF. The structure was verified by UV-Vis, CD, FTIR, AFM and WAXD.

Comment

The authors reported a useful design rationale for the assembly of a multiple-component polymeric system. The helical structure may lead to new opportunities to materials research, such as enantioselective polymeric catalysis (Angew. Chem. Int. Ed. 2007, 46, 5885), facilitated energy-transfer processes, and improved mechanical strength.
