Heena Meroliya, Vidya Kalyankar, and Shobha Waghmode
A new two fluorescent derivatives of Lawsone have been synthesizedand used for CO2 utilization reactions after complexation with different cations such as Zn2+ Fe2+ and Ru2+. Among the all divalent cations studied receptor molecule La shows increase in absorbance as well as fluorescence towards Zn2+ ion. Ligand shows 1:2 stoichiometry of the complex formed between ligand and Zn2+ Fe2+ and Ru2+, which is demonstrated by absorption spectroscopy, elemental analysis and thermo gravimetric analysis. Absorption studies shows better results to explain the role of ligand for selective sensing of Zn2+ has been worked out by comparing data with that of control molecule. The complexes of Zn2+ Fe2+ and Ru2+ with ligand have been further studied for utilization of CO2. Complex synthesized have been tested for carrying out synthesis of N,N-dimethylformamide (DMF) and methyl formate (MF). Catalyst efficiently converts CO2 into DMF and MF with 42% and10% yield respectively. Additionally, the catalyst prepared found to be stable in air and can easily been prepared. XRD, TGA, FTIR, and TPD techniques been used to characterized the prepared catalysts.
