Switchable supramolecular helices for asymmetric stereodivergent catalysis

Circular dichroism data corresponding to Figure 2 of the paper. Measurements were performed on a Jasco J-1500 spectrometer equipped with a Peltier thermostated cell holder and Xe laser. CD spectra were recorded at 313 K with the following parameters: 50 nm.min-1 sweep rate, 0.05 nm data pitch, 2.0 nm bandwidth, and between 400 and 275 nm. The solutions were placed into cylindrical spectrosil quartz cell of 0.05 mm pathlength (Starna® 31/Q/0.05).
