Developing near-infrared (NIR) fluorescence probes for detection of intracellular viscosity is still sufficiently challenging. In this work, three kinds of D-A-D type naphthyl and 2,1,3?benzoxadiazol hybrid NIR dyes functionalized with amino (NY1), N?methylamino (NY2) and N,N?dimethylamino (NY3) groups for intracellular micro-viscosity detection were designed and synthesized. All the probes exhibited very weak NIR emission in low viscosity environment and obvious fluorescence enhancement with the increased viscosity. Different substituent groups had a high impact on the photophysical properties and response sensitive of the probes to viscosity. The structure-property relationships were systematic investigated. The results showed that stronger electron-donating ability and larger steric effect of N,N?dimethylamino led to a narrower energy gap and more sensitive to viscosity environment. Therefore, NY3 exhibited higher signal noise ratio for viscosity detection and was successfully applied for imaging the changes of intracellular micro-viscosity. This work provides an efficient way to design powerful NIR fluorescence probes for viscosity detection.

The invention relates to a method for viscosity detecting near-infrared fluorescence probe and its preparation and use, which belongs to the detection field. The material of the invention is cheap, simple and convenient operation, mild reaction conditions, low production cost, convenient industrial a compound with larger Stokes displacement can be used for measuring the viscosity of the near-infrared probe, and by mass spectrometry, nuclear magnetic resonance hydrogen and carbon spectrum characterization means such as nuclear magnetic resonance to the target compound to carry out the precise structure characterization. Such probe can be applied to human health/disease detection and diagnosis, the use of these probe can detect changes in the viscosity of the cell, thus can be achieved to the disease early warning. The probe has a better chemical stability, biological compatibility and selective. Laser confocal imaging experiments show that the probe has a better cell permeability, toxic to cells and organisms, can realize the cell level detecting and indicating the viscosity of the viscosity change, can further application disease early detection research.
