The following was left over from supramolecular chem. Maybe it fits somewhere else?
Anion complexation has used to construct several polymers that adopt a double helix conformation much like [[DNA]].<ref name=dblhelix>{{cite journal | vauthors = Liu J, Lam JW, Tang BZ | title = Acetylenic polymers: syntheses, structures, and functions | journal = Chemical Reviews | volume = 109 | issue = 11 | pages = 5799–867 | date = November 2009 | pmid = 19678641 | doi = 10.1021/cr900149d }}</ref> In one example, they incorporated [[platinum]] to create a double helical metallopolymer.<ref name=mettalopoly>{{cite journal | vauthors = Ikeda M, Tanaka Y, Hasegawa T, Furusho Y, Yashima E | title = Construction of double-stranded metallosupramolecular polymers with a controlled helicity by combination of salt bridges and metal coordination | journal = Journal of the American Chemical Society | volume = 128 | issue = 21 | pages = 6806–7 | date = May 2006 | pmid = 16719458 | doi = 10.1021/ja0619096 }}</ref> Starting from their monomer and platinum(II) biphenyl, their metallopolymer self assembles through a series of [[ligand exchange]] reactions. The two halves of the monomer are anchored together through the salt bridge between the deprotonated carboxylate and the protonated nitrogens.
