资源简介：
The absolute configurations of 1,n-glycols (n = 2–12, 16) bearing two chiral centers were rapidly determined via exciton-coupled circular dichroism (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 porphyrin tweezer relative to the diol guest molecule is suggested as the mode of complexation.
