Synthesis of Novel Rhodium Complex of Biphenylic-Imidazole-Phenanthroline and Photophysical Analysis of Metal Ions Selectively for Pb2+

Abstract

A novel rhodium biphenylic-imidazole-phenanthroline metal-organic complex has been synthesized and the photophysical properties were studied against different metal ions. The rapid and sensitive detection of metal ions have an important impact on making the various environmental, biological and chemosensor devices. The new chemosensing properties have shown the affinity for Pb2+ toward Rhodium biphenyl-imidazole phenanthroline 6. These studies significantly conceded out that the UV/Vis and flourescent characteristic of the receptor has selectively responded at 344 nm with absorbance of 0.341 to the Pb2+, it is also obviously evident from the partial H-1-NMR results that the disappearance of NH at 7.129 and 10.081 ppm respectively. The remaining metal ions appeared small difference in their hypso- and hyperchromic shifts of UV/Vis results. Furthermore characterization and analytical studies of metal-organic complexes as chemosensors for different metal ions such as Ca2+, Cs+, Cu2+, Fe3+, K+, Mn2+, Na+, Pb2+, Sb+, Sn2+, Sn4+, and Zn2+ were carried using NMR, MS-ESI, Fluorescence and UV/Vis spectroscopic technique.
