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.
摘要
我们介绍了一种新型的笼状谷氨酸，它以钌联吡啶为核心，在波长高达 532nm 的可见光照射下发生均裂裂解，在不到 50ns 的时间内生成游离谷氨酸。谷氨酸的光释放也可以通过 800nm 的双光子（2P）激发有效地发生，其功能截面为 0.14GM。
