摘　　要：为能够快速灵敏地反应润滑黏度变化情况,满足实际应用需求,通过分析CPA-TPA和DCPE-TPA两种聚焦诱导荧光探针检测方法,对比研究其在润滑油中的荧光发射强度,结果表明:这两种探针都可用于检测润滑油黏度变化,且随着润滑油黏度的增加,其分子荧光发射强度均随之增大,但是在相同黏度的润滑油中,分子转子旋转阻力更大的CPA-TPA分子的荧光发射更强,明显高于DCPE-TPA,其对黏度的响应性能更好。In order to quickly and sensitively reflect changes in lubricating viscosity and meet practical application needs,the fluorescence emission intensity of CPA-TPA and DCPE-TPA focusing induced fluorescence probe detection methods in lubricating oil was compared and studied.The results showed that both probes can be used to detect changes in lubricating oil viscosity,and their molecular fluorescence emission intensity increases with the increase of lubricating oil viscosity.However,in lubricating oil with the same viscosity,CPA-TPA molecules with higher molecular rotor rotation resistance have stronger fluorescence emission,significantly higher than DCPE-TPA,and better response performance to viscosity.
