摘要

两种基于振动诱导发射的荧光团，即DPAC-Me和DPAC-CF3，表现出三重荧光发射，并在很宽的粘度范围内表现出对粘度的高灵敏度。除了正常的粘度范围（1-1000 cP）外，DPAC-CF3在非常低的范围（0.3-1 cP）和非常高的范围（1000-72 - 330 cP）对粘度也表现出很高的敏感性。

A highly sensitive triple ratio viscosity probe for fluorescence response across ultra-wide viscosity ranges†

Two vibration-induced-emission-based fluorophores, namely DPAC-Me and DPAC-CF₃, exhibit triple fluorescence emissions and demonstrate high sensitivity to viscosity across a broad viscosity range. In addition to the normal viscosity ranges (1–1000 cP), DPAC-CF₃ also shows high sensitivity to viscosity in both very low ranges (0.3–1 cP) and extremely high ranges (1000–72 330 cP).
