摘要：
Anion to nerve agent simulant detection by relay recognition has been designed and realized for the first time with sequence specificity (F- -> DCNP) via a fluorescence "off-on-on" mechanism. The discrimination of DCNP and DCP via a CIFE (cyclization induced fluorescence enhancement) mechanism has also been demonstrated here. Test strips based on the sensors with F- and DCNP are fabricated, which can act as convenient and efficient nerve agent and F- test kits. The origin of the sequence specificity of different fluorescence recognition was revealed through single X-ray crystal and NMR analysis.
