Abstract
Porous materials have been widely studied for encapsulation and controlled release of active species for packaging applications. This study examines the encapsulation efficiency of hexanal in γ-cyclodextrin metal organic frameworks (γ-CDMOF) for potential active packaging applications. γ-CDMOF was synthesized and hexanal was encapsulated in the MOF using a vapor diffusion process. The synthesized MOF was characterized both before and after the encapsulation of hexanal using x-ray diffraction (XRD), scanning electron microscopy (SEM), differential scanning calorimetry (DSC), fourier transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TGA). The diffraction peaks of various planes obtained from XRD characterization matched the theoretically calculated values. We identified the most stable docking sites using energy minimization calculations. FTIR and computational studied indicated hydrogen bonding interactions play a significant role in the stabilization of hexanal and γ-CDMOF inclusion complex. TGA characterization results revealed an encapsulation efficiency of about 15%. DSC and SEM study also supported encapsulation of hexanal in γ-CDMOF.
期刊介绍:
The Journal of Inclusion Phenomena and Macrocyclic Chemistry is the premier interdisciplinary publication reporting on original research into all aspects of host-guest systems. Examples of specific areas of interest are: the preparation and characterization of new hosts and new host-guest systems, especially those involving macrocyclic ligands; crystallographic, spectroscopic, thermodynamic and theoretical studies; applications in chromatography and inclusion polymerization; enzyme modelling; molecular recognition and catalysis by inclusion compounds; intercalates in biological and non-biological systems, cyclodextrin complexes and their applications in the agriculture, flavoring, food and pharmaceutical industries; synthesis, characterization and applications of zeolites.
The journal publishes primarily reports of original research and preliminary communications, provided the latter represent a significant advance in the understanding of inclusion science. Critical reviews dealing with recent advances in the field are a periodic feature of the journal.
