Extended Data Fig. 1: HPLC, CD spectra, fatigue resistance and thermal stability comparisons: intrinsic chirality vs. extrinsic chiral groups.
From: Digital photoprogramming of liquid-crystal superstructures featuring intrinsic chiral photoswitches
a, Chiral HPLC chromatograms of (M)-2o, (CH3CN, monitored at the isobestic point of 340 nm). b, Chiral HPLC chromatograms of (M)-3o (CH3CN : H2O=80 : 20, 0.5 mL min−1, monitored at the isobestic point of 303 nm). c, d, The circular dichroism spectra of (M)-2o and (M)-3o. e, f, Fatigue resistance of (M)-2o and (M)-3o in tetrahydrofuran at 2.0 × 10−5 M. The photoswitches were irradiated with UV (λ = 313 ± 10 nm) light and visible (λ > 480 nm) light and the detected value is the maximum absorption in the visible region.
