Acid-base balance plays a key role in regulating biological processes, and the cells must stabilize the pH within a certain range, and pH instability will cause a series of diseases. Therefore, tracking intracellular pH changes was important for understanding physiological and pathological processes. Fluorescent probes were favored by researchers as simple, fast and efficient pH detection tools, which have potential research value. In this work, a ratiometric and colorimetric sensor based on rhodamine (Rh-TPE) was fabricated for mon
