Synthesis and Optical Properties of Newly Synthesized 3,3’-((4-Methoxyphenyl) Methylene) Bis(4-Hydroxy-2H-Chromen-2-One) Molecule

In this report, a facile and efficient protocol has been followed for the synthesis of novel 3,3’-((4-methoxyphenyl)methylene) bis(4-hydroxy-2H-chromen-2-one) via a one pot reaction of aryl aldehydes with 4-hydroxycoumarin and in the presence of ethanol at 800C. The synthesized molecule is being further tested for structural confirmation with nuclear magnetic resonance and Fourier transform infrared spectroscopic technique. From the obtained result of 1H NMR spectroscopy it has been confirmed that the synthesized molecule is stable with ten electron signal. The optical absorption measurement was carried out in order determine the optical property of the synthesized molecule such as the bandgap and molar extinction coefficient. Further the bond angles and bond lengths of the molecule was estimated theoretically using a software in order to confirm the structure with the experimental result. From over all outcomes the molecule exhibited a considerable result in order to derive the optical device application.
