Photoswitching of Site-Selective RNA Scission by Sequential Incorporation of Azobenzene and Acridine Residues in a DNA Oligomer

Figure 3

Time dependence of UV-VIS absorption of 1/2 complex. The spectra were measured 0 (black), 1 (purple), 6 (blue), 11 (green), 16 (yellow), and 21 h (orange) after UV irradiation at pH 7.5 and 37°C. The spectrum after heat shock (trans-dominant) is drawn in red. The dashed line represents the spectrum of 1/3 complex without azobenzene.
