n-glycols (n = 2-12, 16) bearing two chiral centers were rapidly determined via exciton-coupled circulardichroism (ECCD) using a tris(pentafluorophenyl)porphyrin (TPFP porphyrin) tweezer system in a nonempirical fashion devoid of chemical derivatization. A unique "side-on" approach of the porphyrintweezer relative to the diol guest molecule is suggested as the mode of complexation.
