Figure 5.
UV-visible spectra of cis, trans-[Pt(bpy)(N3)2(OH)2] (4), cis, trans-[Pt(phen)(N3)2(OH)2] (5) and trans, trans, trans-[Pt(N3)2(OH)2(py)2] (6) after UVA irradiation for 0 (–), 1 (
), 5 (
), 15 (
), 30 (
), 60 (
) and 120 (
) min. The arrows denote an increase or decrease of absorbance with increasing irradiation time.
