A deep-red emission fluorescent probe for detection of viscosity in living cells and mice

[摘要] Herein we constructed a deep-red emission fluorescent probe HY for the monitoring of viscosity variation. The probe HY exhibited high selectivity and sensitivity. In 90% glycerol solution, the fluorescence intensity of HY increased significantly compared with pure methanol solution. More importantly, the probe HY has been successfully applied for visualizing viscosity variations in cells and living mice.
