A novel compound containing indenoquinoxaline and pyrazole units in quantitative yield, 4-((11H-indeno[1,2-b]quinoxalin-11-ylidene)amino)-1,5-dimethyl-2-phenyl-1H-pyrazol-3(2H)-one (4) was synthesized and characterized using FT-IR, 1H NMR, 13C NMR, and mass spectral data and elemental analysis. The colorimetric sensor property of the title compound in aqueous acetonitrile solution for use in the detection of various metal cations such as Cu2+, Hg2+, Ni2+, Mn2+, Zn2+ and Fe2+ was investigated through changes in the absorption of the UV-vis spectrum. A well-defined discoloration that could be detected with the naked eye was also observed. Due to the presence of heteroatoms in the molecular structure and their conformations, it was observed that the title compound in aqueous acetonitrile solution showed receptor properties against the Cu2+, Hg2+, ions among these ions.
