RuBiGABA-2: A hydrophilic caged GABA with long wavelength sensitivity

We have devised a new caged GABA based on ruthenium bipyridyl coordination chemistry. This phototrigger delivers GABA upon irradiation with wavelengths up to 532 nm undergoing heterolytic photocleavage, in a clean and very fast (a few nanoseconds) photoreaction. With an absorptivity coefficient εMAX...
