Abstract

Quinolones are synthetic compounds which are part of the antibiotics family. Quinolines were first obtained in 1834 and isoquinolines were obtained from coal tar in 1885. In this paper, exchange and correlation energies of C26H23ClN4 and C26H23FN4 are calculated by using the DFT methods with STO-3G, 3-21G, 6-31G, 6-311G and 6-21G basis sets. The optimized structure and electronic properties calculations for the studied molecule have been performed by using Gaussian 09 program. A mathematical equation of second grade was exploited for the correlation and exchange energy with the number of primitives. The chemical reactivity of the C26H23ClN4 and C26H23FN4 have been investigated at B3LYP/6-31G (d) level of theory. The band gap energy, total energy (E), chemical hardness (η), electronic chemical potential (μ), and global electrophilicity index (ω), ionization potential (IP) and electron affinity (EA) for the C26H23ClN4 and C26H23FN4 have been calculated for the chemical activity of the above molecules. According to the results, the C26H23ClN4 molecule is more stable and the chemical activity of C26H23FN4 is greater.
