Quinoline-based ratiometric fluorescent probe for detection of physiological pH changes in aqueous solution and living cells

Herein, a novel quinoline-based fluorescent probe DQPH has been developed for ratiometric detection of subtle pH fluctuation in biosystem. Upon altering the pH from 4.50 to 9.00, the emission spectra exhibit a large hypsochromic shift (57 nm) and the ratio of fluorescence intensity (F531 nm/F588 nm)...
