Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 1127-45-3, is researched, SMILESS is OC1=CC=CC2=CC=C[N+]([O-])=C12, Molecular C9H7NO2Journal, Sensor Letters called 2,8-Dihydroxyquinoline based sensitive fluoroionophore towards Cu2+ ion, Author is He, Chunlian; Li, Cheng; Li, Zhiguang; Li, Huanyin; Xiang, Jiannan; Yan, Zhengli, the main research direction is dihydroxyquinoline fluoroionophore copper ion determination.Product Details of 1127-45-3.
Novel water soluble quinoline derivatives 1a∼1d were synthesized from 8-hydroxyquinoline and the fluorescence of these compounds had been quenched by Cu2+ or Fe3+ in absolute water. The fluorescence of 1a was quenched by 93% with addition of 50 μM of Cu2+ in absolute water and 75% in the presence of 50 μM of Fe3+ with the quenching ratio (Cu2+:Fe3+) of 1:0.80, showing much higher sensitivity and selectivity of Cu2+ to Fe3+. The presence of some other metal ions such as K+, Ca2+, Zn2+, Al3+, Mn2+, Fe2+, Ba2+, Co2+, Ni+, Cr3+, Cd2+, Cu2+, Hg2+, Pb2+, Sn2+, Na+ and Mg2+ had little influence on the selectivity and sensitivity of Cu2+. The easily available 1a could be considered a potential fluorescence sensor for Cu2+.
As far as I know, this compound(1127-45-3)Product Details of 1127-45-3 can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
