pH fluorescent probes for cellimaging was developed. The probes showed turn “On” fluorescence response upon acidification brought by a modulation of photoinduced electron transfer (PET) from the N,N-dialkyl aniline substituent to the quinolizinium core skeleton. These novel PET-based pH fluorescent probes displayed tunable emission properties in between 478 and 509 nm. Also, the probes exhibited tunable
