Helical folding of poly(naphthalenecarboxamide)s with aliphatic side chains in hydrophobic solvents is investigated. The CD spectra of the polyamide showed a predominant left-handed helical structure in chloroform, THF, and cyclohexane. Furthermore, the sergeants and soldiers experiment in cyclohexane showed a clear chiral amplification. These results indicate that the helical structure was stabilized by an intramolecualr self-association based on the solvophobic effect, and that there is cooperativity between the monomer units constituting the helical structure.
