Hetero-double-helix formation by an ethynylhelicene oligomer possessing perfluorooctyl side chains

10.1021/jo8010057

The study focuses on the synthesis and characterization of ethynylhelicene oligomers with perfluorooctyl side chains, ranging from monomers to pentamers. Utilizing circular dichroism (CD) and vapor pressure osmometry (VPO), the research demonstrates the formation of a helix-dimer, particularly in the case of the pentamer within trifluoromethylbenzene at low temperatures and specific concentrations. A comparison between the perfluorooctyl and decyloxycarbonyl side-chained pentamers reveals that the former exhibits lower solubility in organic solvents, forms a more thermodynamically stable helix-dimer, and shows an inverted mirror image CD spectrum. Additionally, the perfluorooctyl pentamer is found to form a hetero-helix dimer with a decyloxycarbonyl pentamer, indicating a higher stability for the hetero-helix dimer over the homo-helix dimers. This work contributes to the understanding of double-helix structures in synthetic oligomers and their potential applications in supramolecular chemistry.
