A simple and efficient ratiometric fluorescent probe 1 for hypochlorite has been rationally constructed based on a novel hypochlorite promoted oxidation of N-alkylpyridinium reaction. Notably, this oxidation reaction was first employed for developing fluorescent hypochlorite probe. Upon addition of hypochlorite, probe 1 presented a ratiometric response, with the emission wavelength displaying a remarkable
We present a ratiometricfluorescentprobe for monitoring pH featuring superb photostability and chemostability. The down-regulation of the intracellular pH during autophagy in living cells induced by various stimuli, including several drugs and starvation, was quantified, which could provide instructive value to construct autophagy models to study the related pathological processes.

successfully utilized for fluorescence imaging of viscosity variations and ONOO− in mitochondria of living cells through different channels. In addition, the results of cellimaging revealed that ONOO− would lead to the increase of viscosity. Taken together, this work provides a potential molecular tool for researching biological functions and interactions of viscosity and ONOO− in mitochondria.
