Synthesis of the New 1-(7-Methoxy-1-benzofuran-2-yl)-3-(4-methylphenyl)prop-2-en-1-one and Controlling of Spectroscopic, Optical and Conductivity Properties by Concentration.

Chalcone derivatives have an important place in science due to their different applications ranging from their semiconductor properties to biological properties. In this work 1-(7-methoxy-1-benzofuran-2-yl)-3-(4-methylphenyl)prop-2-en-1-one (2) has been prepared by condensation of 1-(7-methoxy-1-benzofuran-2-yl)ethanone with 4-methylbenzaldehyde in basic medium. The chemical structure of 2 was confirmed by elemental analysis, FT-IR, 1H NMR and 13C NMR. UV spectroscopic characteristics, absorption band edges, optical band gaps, refractive indices, environmental behaviors and conductivity properties of 2 in solutions at different concentrations were investigated in detail. With the concentration, we examined how the spectroscopic, optical and conductivity properties of 2 have changed and can be controlled.
