Notes:
The crystallographic interactions between the toluenesulfonate-substituted diacetylene 2,4-hexadiynylene di-p-toluenesulfonate (TS), its corresponding polymer (PTS) and polyethylene (PE) have been established in detail with the help of the polymer decoration technique. Although monomer and polymer are known to be isomorphous, the decoration patterns observed on their (100) crystal surface differ significantly, revealing some subtle structural changes on solid-state polymerization. The single and twofold orientations obtained on TS and PTS, respectively, are discussed and shown to be of epitaxial character. The PE contact planes for the two decoration orientations are however, significantly different, since the chain packing distances at play are 5,26 Å (or 4,94 Å) and 7,47 Å, respectively. From the very close similarity in crystal structures, it is anticipated that favourable interactions may also exist in many other polydiacetylene/polymer binary systems.
