	1	A Novel Tetraphenylethylene-Based“Turn On”Fluorescent Sensor with Highly Sensitive Response to Mercury Ions显示文摘A novel 4-tert-butyl-N’-(4-(1,2,2-triphenylvinyl)benzylidene)benzohydrazide(TBB)was successfully synthesized in simple one-step process.It was characterized by FT-IR,1H NMR,13C NMR and HRMS.Its fluorescence sensing ability to 15 metal ions was investigated.Weak emission from TBB could be efficiently increased by trace Hg^2+,through coordination reaction between TBB and Hg^2+ with'turn on'character.The fluorescence intensity of TBB/Hg^2+([TBB]=3.0×10^–6 mol/L,[Hg2+]=1.3×10^–4 mol/L)was 7.5 times higher than that of TBB.This TBB sensor exhibited high selectivity for Hg^2+ and other metal ions did not interfere in this determination.The limit of detection was 0.566μmol/L(S/N=3).The experimental results showed that this TBB sensor could sensitively respond to Hg^2+ within concentration range(from 5×10–6 mol/L to 1.3×10^–4 mol/L).
