Multiwavelength Control of Mixtures Using Visible Light-Absorbing Photocages

Selective deprotection of functional groups using different wavelengths light is attractive for materials synthesis as well achieving independent photocontrol over substrates in biological systems. Here, we show that mixtures recently developed visible light-absorbing BODIPY-derived photoremovable protecting (PRPGs) and a coumarin-derived PRPG can undergo wavelength-selective activation, giving optical control mixture photocaged biologically benign long-wavelength light.
