“…36 They proposed that, at the structural level, the alkyl chains of the two surfactants form inclusion complexes with b-CD which is consistent with our explanation. These results showed that our CD-PAH microspheres have promising potential applications in removing surfactants and POPs in aqueous solutions.…”

We have fabricated nanoporous polyallylamine hydrochloride (PAH)-cyclodextrin co-polymeric microspheres using epichlorohydrin as a cross-linking agent. The structure and morphology of the microspheres were studied by optical and electron microscopy and FT-IR spectrometry was used to confirm the presence of cyclodextrin in the co-polymer. The encapsulating capability of these molecularly porous microspheres was tested by loading them with two fluorescing dyes whose localization within the microspheres was examined by Laser Scanning Confocal Microscopy (LSM). We tested the capacity of the microspheres to remove surfactants such as cetyltrimethyl ammonium bromide (CTAB), Sodium Dodecyl Sulphate (SDS) and organic dyes like Indophenol Blue from aqueous solutions. These results were confirmed using surface tension measurements and UV-vis spectroscopy. The CD-copolymeric microspheres showed significant capacity for encapsulation of molecules of varying polarities and different hydrophobicities, which makes them attractive for applications in a wide range of areas such as agrochemicals, water purification, pharmaceuticals, drug delivery, separation science and cosmetics.

“…The infrared band usually shis or the intensity changes aer the guest molecule is encapsulated by b-cyclodextrin. 39 In this study, we determined the FT-IR spectrum of rubropunctatin, bcyclodextrin, the physical mixture and the rubropunctatin/bcyclodextrin inclusion complex from 4000 to 500 cm À1 .…”

“…CDs are well known series of macro cyclic oligosaccharides resulting from the degradation of starch by bacterial enzymes [2]. Generally, CDs are composed of 6, 7, or 8 glucose units connected by α-1,4-glucosidic linkages which are categorized as α-, β- and γ-CD, respectively [3–6]. Among these CDs, β-Cyclodextrin (β-CD) has been chosen for this study since its cavity size is suitable for guest molecules with molecular weights between 200 and 800 g/mol [7,8].…”

This study focuses on the synthesis and characterization of the inclusion complex of β-Cyclodextrin (β-CD) with dicationic ionic liquid, 3,3′-(1,4-Phenylenebis [methylene]) bis(1-methyl-1H-imidazol-3-ium) di(bromide) (PhenmimBr). The inclusion complex was prepared at room temperature utilizing conventional kneading technique. Proton (1H) NMR and 2D (1H–1H) COSY NMR were the primary characterization tools employed to verify the formation of the inclusion complex. COSY spectra showed strong correlations between protons of imidazolium and protons of β-CD which indicates that the imidazolium ring of PhenmimBr has entered the cavity of β-CD. UV absorption indicated that β-CD reacts with PhenmimBr to form a 2:1 β-CD-PhenmimBr complex with an apparent formation constant of 2.61 × 105 mol&−2 L2. Other characterization studies such as UV, FT-IR, XRD, TGA, DSC and SEM studies were also used to further support the formation of the β-CD-PhenmimBr inclusion complex.
