Enantiopure, monodisperse alleno-acetylenic cyclooligomers were synthesized. The single-crystal x-ray structures of the cyclic trimer and hexamer were resolved, providing insights into the symmetry of these mols. Electronic CD (ECD), ORD, Raman spectroscopy, and vibrational CD (VCD) data were analyzed with the aid of theor. calcns. This multidimensional approach ultimately provided general guidelines that are useful for designing carbon-rich compds. with intense chiroptical properties.
