a HPLC chromatograms before and after being resolved. HPLC conditions: eluent = 50% CH3OH/CH2Cl2, temperature = 40 °C, flow rate = 1 mL/min. b CD spectra of (+)275-[4]CQ (CH2Cl2, 298 K, 3.02 × 10–6 M) and (–)275-[4]CQ (CH2Cl2, 298 K, 3.97 × 10–6 M). The theoretical CD spectrum was obtained by TD DFT calculations (B3LYP/6-31 G(d,p)) for the (P)-isomer of methyl-substituted [4]CQ as the model.
