| Summary: | Abstract The detection of gamma-butyrolactone (GBL) is crucial in medicinal chemistry due to its role as a precursor to gamma-hydroxybutyrate (GHB) and its potential for misuse. This study presents a sensor for GBL detection based on fullerene C24 and its beryllium-, calcium-, and magnesium-doped derivatives. Using density functional theory (DFT) and time-dependent DFT (TD-DFT), we optimized the structures and analyzed their electronic, optical, and quantum properties. Key parameters such as energy gaps, chemical reactivity, dipole moments, and adsorption energies were evaluated. Among the studied systems, magnesium-doped C24 (MgC23) exhibited the highest reactivity, a pronounced red shift in UV absorption upon GBL complexation, and an optimal balance of adsorption energy and recovery time. These results highlight MgC23 as a promising candidate for sensitive and efficient GBL detection in pharmaceutical and forensic applications. |
