Easily accessible green-light activatable (>500 nm) photocages based on red-shifted, π-extended coumarin scaffolds are developed with uncaging efficiencies similar to those of recently introduced BODIPY derivatives. The photocages possess increased aqueous solubility, high absorption coefficients within the 450-600 nm range, and exceptionally high two-photon cross sections.
