Abstract

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 532nm, yielding free glutamate in less than 50ns. Glutamate photorelease occurs also efficiently following two-photon (2P) excitation at 800nm, and has a functional cross section of 0.14GM.
