Abstract: Using Lindqvist hexamolybdate as an inorganic composite and aniline as an organic composite, a covalently linked hexamolybdopolyacid-aniline hybrid solid was synthesized by dehydration method with dicyclohexyl carbodiimide. The compound was characterized by 1HNMR,13CNMR, IR and UV-Vis spectroscopy. The UV-Vis spectra of the compound showed that the apparent red-shifted band (about 37 nm) was observed compared with aniline, which confirmed that the triple bond formed between Mo and N, and further increased the conjugation of the system. IR spectra displayed that the compound kept the basic structure of Lindqvist polyacid. UV-Vis spectroscopy was used to detect different concentrations of Vitamin C. It was found that the absorbance of the hybrid solution didn't change significantly after repeated cycles, indicating that the UV-visible probe can be recycled.
