Effect of β-cyclodextrin on benzophenones and its impact on UVR filtration of cotton fabric through ‘guest absorber—host enhancer’ mechanism
The impact of β-CD on 4 benzophenones (BPs) [namely, BP, HBP, d-HBP, t-HBP] and its resultant effect on the ultraviolet protection factor (UPF) of poplin cotton fabric are tested. Drastic enhancement in the UPF values for BPs:β-CD complexes treated fabrics is noticed (than the untreated/fabric treated with free BPs). The impact of β-CD on the tautomerism of hydroxyl substituted BPs are demonstrated by investigatingthe guest (BPs:absorbers)-host(β-CD:enhancer) process. Orientation of -OH substituted benzene towards 1° rim and positioning of C = O group of BPs in the middle of β-CD could be attributed to the steric effect driven preference of the guest molecules for achieving a rigid fit. Rigid fit rendered by β-CD improves the photostability of BPs and dissipates UVR efficiently through keto-enol tautomerization. With the highest UPF (= 51) d-HBP:β-CD complex is identified as a potential application material for producing sun-protective clothing.
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.
