Despite the fact that n-corannulene oligomers (n = 1-4) have a variety of electronic and optical properties, including ability to be tuned potential used as light-harvesting materials, there has not been computational assessment their structural, electronic, properties. Herein, evaluation concerned materials regarding potent use in solar cell technology conducted via DFT/CAM-B3LYP M062X/6-311+G level theory. It was observed calculated 1st frequency n-Corannulene were 144.15, 106.36, 48.96 42.21 respectively. Notably, computed cohesive energy value increased number Corannulene units increases while characteristics revealed chemical activity structures rose. Both calculation techniques demonstrate HOMO decreasing LUMO based on external electric field (EF) effect. The findings demonstrated EF intensity increases, gap (Eg/eV |EHOMO-ELUMO|) these molecular systems decreases which can attributed decrease electron transfer barrier. 4-Corannulene showed highest wave length adsorption for investigated compound at 546.18 nm, with oscillator strength 0.2708 lowest transition 2.2700 eV, arising from S0-S1 (H-L) major percentage contribution 93.34 % comparison compounds. We are hopeful this research will help experimental researchers understand n-Corannulene, specifically 4-corannulene, powerful material applications ranging cell, photovoltaic properties many others.

Abstract Fluvoxamine has been proven in studies to improve the immune system by reabsorbing serotonin and be beneficial limiting spread of covid‐19 (in early stages disease). The interaction between pristine fluvoxamine drug serotonin, as well NO 2 /NH doped was investigated this work using quantum theory atom molecule (QTAIM) density‐functional (DFT) at B3LYP/6‐311+G (d,p) (gas phase water media) computational level. NH doping on significantly increased adsorption energy improved dipole moment, solvent energy, chemical hardness/softness, charge/energy transfer. On other hand, according results study, compared had no significant effect electronic properties such HOMO/LUMO orbital its gap. From results, binding most stable structure (Complex‐A) measured 12.59 11.65 kcal/mol. Based analysis, an assessment stability studied systems gas reveals following trend: Fluvoxamine‐NH2>Fluvoxamine‐NO2>Fluvoxamine‐NH2/Ser>Fluvoxamine‐NO2/Ser, with corresponding gaps 4.12, 2.65, 1.98, 1.63 eV, respectively. Therefore, is a harmless does not change drug. It seems that increasing absorption functional group can help reduce therapeutic dose make more effective.
