Abstract
AbstractInduced circular dichroism (CD) spectra of the m‐diethynylbenzene macrocycles (S)‐2 and (R)‐2 that have exoannular chiral side chains are observed in a methanol/chloroform (8:2) solution, indicating the formation of chiral, helical aggregates in solution. Solid films prepared on the surface of quartz substrates by spin‐coating solutions of (S)‐2 also exhibit CD signals that are remarkably dependent on the solvent used for the spin‐coating. The relationship between the CD spectra and the morphology of the solid films observed by atomic force microscopy is discussed.
