(a) Molecular structures of (S)-CPDI-Ph and (R)-CPDI-Ph. (b) Experiment and Calculation results of IR and VCD spectra of CPDI-Ph. Solid lines show experiment data of CPDI-Ph and blocks show calculation results for (R)-CPDI-Ph. (c) UV-vis spectra of (S)-CPDI-Ph and (d) CD spectra of enantiomeric CPDI-Ph in THF/water mixed solution (1.0 × 10−5 M) with different f w.
