A fast ruthenium polypyridine cage complex photoreleases glutamate with visible or IR light in one and two photon regimes

We introduce a new caged glutamate, based in a ruthenium bipyridyl core, that undergoes heterolytic cleavage after irradiation with visible light with wavelengths up to 532. nm, yielding free glutamate in less than 50. ns. Glutamate photorelease occurs also efficiently following two-photon (2P) exci...
