Abstract
As an important cellular micro environmental parameter, viscosity could reflect the status of living cells. Small molecular fluorescent probe is a vital tool to measure the change of viscosity in living cells. A novel fluorescence probe ZL-1 with a large Stokes shift (in methanol it reached to 153 nm and in glycerol it reached to 125 nm) and excellent sensitivity toward viscosity was developed. The sharp enhancement of the emission intensity for the probe ZL-1 from low viscous methanol to high viscous glycerol indicated the probe ZL-1 could be respond to the viscosity variations. Moreover, the probe ZL-1 has been successfully utilized to detect of viscosity variations in living cells.
