51. Temperature dependence of the dissymmetry ratio of PS-1 and PS-2 in isooctane is shown in the Supporting Information section (Figure S1).
52. Many researchers pointed out the difficulty of measuring and interpreting the CD spectra of cast films. The linear dichroism (LD) signal may contribute to the observed apparent CD spectra of the films and makes it difficult to estimate the real CD enhancement of the films. Concerning these problems, we provided Supporting Information for the rotation angle dependence of the CD and LD spectrum of PS-1 cast films as shown in Figure S2.
