Abstract
The current investigation uses the density functional theory (DFT) with the M06-2X functional and 6-31G (d, p) basis set to examine the interaction between trichlorfon (TCF) and the cavity of β-cyclodextrin (β-CD). The primary objective of our study is to gain an insight into the molecular characteristics of this interaction by analyzing quantum parameters such as the HOMO–LUMO gap, the HOMO, and the LUMO. Two potential encapsulation modes, designated as A and B models, were identified for TCF. The thermodynamic assessments including complexation energies and alterations in enthalpy, entropy, and Gibbs free energy indicate a stable and advantageous encapsulation procedure. The independent gradient model (IGMH) provides insights into the non-covalent interactions in developing the TCF@β-CD complex. The observed stability can be mainly attributed to a significant intermolecular hydrogen bond emphasized by the NBO and EDA and weak van der Waals forces. The results of our study indicate that β-CD as macrocycle has the potential to be a suitable trap for trichlorfon.
期刊介绍:
Structural Chemistry is an international forum for the publication of peer-reviewed original research papers that cover the condensed and gaseous states of matter and involve numerous techniques for the determination of structure and energetics, their results, and the conclusions derived from these studies. The journal overcomes the unnatural separation in the current literature among the areas of structure determination, energetics, and applications, as well as builds a bridge to other chemical disciplines. Ist comprehensive coverage encompasses broad discussion of results, observation of relationships among various properties, and the description and application of structure and energy information in all domains of chemistry.
We welcome the broadest range of accounts of research in structural chemistry involving the discussion of methodologies and structures,experimental, theoretical, and computational, and their combinations. We encourage discussions of structural information collected for their chemicaland biological significance.
