文摘
The modeling of the molecule 1,4-bis(3-carboxyl-3-oxo-prop-1-enyl) benzene has been carried out to study the electronic, optoelectronics, photonic and thermodynamics properties using Hartree–Fock, density functional theory (B3LYP) and MP2 (Möller–Plesset perturbation theory second-order) with the 6-31G and 6-31+G** basis sets. The dipole moment (µ), polarizability (〈α〉), first hyperpolarizability (βmol), dielectric constant (ε), electric susceptibility (χ), refractive index (η) and thermodynamics properties of this molecule have been calculated using the same level of theory. The small values of ε, and LUMO–HOMO energy gap, and the high values of χ, η, MR, 〈α〉 and (βmol) show that the molecule has very good electronic, optoelectronic and photonic applications. The results of this study show that this molecule is an interesting pi-conjugated molecule whose electronic structure and properties can be regulated over a wide range by variation in backbone structure, by side group substitution, and through intramolecular hydrogen bonding.
