Figure 1

Changes in electronic absorption profiles of DMF solution of 1 (2.2 × 10−6 M): (1, vertical bars)—as-prepared solution; (2)—after irradiation of the solution (1) with the wavelength 408 nm for 5 min.; (3)—after mechanical shaking of the solution (2); (4, horizontal bars)—after irradiation of the solution (3) with the wavelength 510 nm for 10 min.
