Spirolactonized Si-rhodamine was prepared as a platform to construct Si-rhodamine-based probes by following the design strategy widely used in rhodamine systems. Among them, the reaction-based probe SiR-Hg was operated for NIR sensing and bioimaging of Hg(2+) in living cells based on the similar irreversible spirolactam ring-opening process to traditional rhodamine derivatives.
