A uracil nitroso amine based colorimetric sensor for the detection of Cu2+ ions from aqueous environment and its practical applications

A simple uracil nitroso amine based colorimetric chemosensor (UNA-1) has been synthesized and screened for its cation recognition ability. Sensor UNA-1 exhibited a high sensitivity and selectivity towards Cu2+ ions in aqueous medium in the presence of a wide range of other competing cations (Ag+, Al3+, Ba2+, Ca2+, Cd2+, Co2+, Cr3+, Cs+, Fe2+, Fe3+, Li+, Mg2+, Mn2+, Na+, Ni2+, Pb2+, Zn2+, Hg2+ and Sr2+). With Cu2+, the sensor UNA-1 gave a distinct color change from colorless to dark yellow by forming a complex of 1:1 stoichiometry. Furthermore, sensor UNA-1 was successfully utilized in the preparation of test strips and supported silica for the detection of Cu2+ ions from aqueous environment.

Molecular and crystal structure of 5,6-diamino-1-methyluracil and 5,6-diamino-1,3-dimethyluracil monohydrate. Semiempirical calculations (AM1 and PM3) on 5,6-diaminouracil derivatives

The crystal and molecular structures of 5,6-diamino-1-methyluracil and 5,6-diamino-1,3-dimethyluracil monohydrate have been determined from X-ray diffraction. Both compounds are planar and the two amino groups have two different conformations. The substituent at the 5 position seems to be a true primary amino group with a strongly sp3 nitrogen, whereas the one at the 6 position is nearly coplanar with the uracil ring, displaying a predominant sp2 character. Semiempirical calculations were made on 5,6-diaminouracil, 5,6-diamino-2-thiouracil and their endocyclic N-methylated derivatives using the AM1 and PM3 hamiltonians. These indicate that the stability decreases on increasing methylation, the 2-thio compounds always being less stable than the 2-oxo ones.
