| 英文摘要 | a lanthanide-complex-based ratiometric luminescence probe specific for peroxynitrite (onoo-), 4'-(2,4-dimethoxyphenyl)-2,2':6',2 ''-terpyridine- 6,6 ''-diyl]bis(methylenenitrilo)tetrakis-(acetate)-eu3+/tb3+ ([eu3+/tb3+ (dtta)]), has been designed and synthesized. both [eu3+(dtta)] and [tb3+(dtta)] are highly water soluble with large stability constants at approximate to 10(20), and strongly luminescent with luminescence quantum yields of 10.0 and 9.9%, respectively, and long luminescence lifetimes of 1.38 and 0.26 ms, respectively. it was found that the luminescence of [tb3+(dtta)] could be quenched by onoo- rapidly and specifically in aqueous buffers, while that of [eu3+(dtta)] did not respond to the addition of onoo-. thus, by simply mixing [eu3+(dtta)] and [tb3+(dtta)] in an aqueous buffer, a ratiometric luminescence probe specific for time-gated luminescence detection of onoo- was obtained. the performance of [tb3+(dtta).] and [eu3+/tb3+(dtta)] as the probes for luminescence imaging detection of onoo- in living cells was investigated. the results demonstrated the efficacy and advantages of the new ratiometric luminescence probe for highly sensitive luminescence bioimaging application. |
