1[12] ane N_3-based BODIPY as a selective and sensitive off–on sensor for the sequential recognition of Cu^(2+) ions and ADP显示文摘A new [12]ane N3-based BODIPY sensor 1 showed highly selective and sensitive recognition of Cu2+ions through fluorescence quenching effect in aqueous solution. The above copper complex solution can further be used as a turn-on fluorescent probe for detecting ADP with high selectivity, and also applied in imaging of living cells.Ying Zhang Yong-Guang Gao You-Di Shi Lian-Qian Tan Jessica S.Yue Zhong-Lin Lu 2015Chinese Chemical Letters2015,26,7:3
2Analysis of insecticide thiacloprid by ion chromatography combined with online photochemical derivatisation and fluorescence detection in water samples显示文摘This study describes a novel application of ion chromatography coupled with post-column photochemically induced fluorimetry derivatisation in alkaline medium and fluorescence detection(IC-hv-FD) for the determination of neonicotinoid pesticide, thiacloprid. In an aqueous medium, this compound showed fluorescence with an excitation maximum at 236 nm and an emission maximum at 353 nm. The 10 mmol/L NaOH with 10%(v/v) acetonitrile solution pumped at flow rate of 1.0 mL/min was used for the chromatographic elution to isocratically separate thiacloprid on an Ion Pac1 AS 11(250 mm 4 mm i.d; 13 mm particle size, Dionex) anion-exchange column. The linear concentration range of application was 0.04–10.0 mg/L, with a relative standard deviation(RSD, n = 7) of 1.7%(for a level of 2.0 mg/L) and detection limit(LOD, S/N = 3) of 9.9 mg/L. The procedure was applied with satisfactory results to the analysis of thiacloprid in ground and lake water samples. Pesticide average spiked recoveries ranged between 95.5% and 114.0%.Qamar Subhani Zhong-Ping Huang Zuo-Yi Zhu Lu-Ye Liu Yan Zhu 2014Chinese Chemical Letters2014,25,3:0
3Tetraphenylethene based zinc complexes as fluorescent chemosensors for pyrophosphate sensing显示文摘We described a serious of zinc complexes that exhibit characteristic fluorescence responses toward pyrophosphate(PPi) and adenosine triphosphate(ATP) in aqueous media. These novel probes exploited tetraphenylethene(TPE) as fluorophore and macrocycle-polyamine(including 1,4,7,10-tetraazacyclododecane and 1,4,7-triazacyclononane) Zn(II) complexes as binding group. These ‘‘OFF–ON'' type probes exhibited promising selectivity and sensitivity to PPi and ATP via a restriction of intramolecular rotation(RIR) mechanism. The detection limit for PPi was found within nmol/L range.Hao-Ran Xu Kun Li Shu-Yan Jiao Ling-Ling Li Sheng-Lin Pan Xiao-Qi Yu 2015Chinese Chemical Letters2015,26,7:0
