Abstract

Abstract: A solvent-dependent probe based on rhodamine was designed, and the sensing behaviors were investigated by spectral properties. Especially, the probe exhibited highly sensitive and selective fluorescence enhancement upon addition of Pd 2+ in ethanol/PBS (2:8, v/v) and ClO − in DMSO/PBS (1:9, v/v) at physiological range with two kinds of mechanisms. Furthermore, the probe was applied for biological imaging which confirmed that it could be used for monitoring Pd 2+ and ClO − in living cells with satisfying results. Graphical abstract: Image 1 Highlights: A solvent-dependent fluorometric dual-mode probe for Pd 2+ and ClO − was got. The mechanisms of two recognition progresses were proposed by experiments and DFT calculations. The probe exhibited excellent fluorescence imaging in living cells.
