From: Hydrazone-based photocages for precise sub-organelle visualization and drug release

a The photocages synthesized by one-step reactions and triggered by light to release their corresponding fluorophore, b design of BW3MP as a sub-organelle imaging tool, and design of FY4STS and BW3STS as prodrugs.
