Synthesis and characterization of host-guest inclusion complex of β-cyclodextrin with 4,4′-methylenedianiline by diverse methodologies

Fe3+-Coordination mediated synergistic dual-network conductive hydrogel as a sensitive and highly-stretchable strain sensor with adjustable mechanical properties

“…In order to prove the structural advantages brought by β-CD, XRD and FTIR analyses of PANI-P(AAm- co -AA)@Fe 3+ synthesized using a normal routine, *PANI-P(AAm- co -AA)@Fe 3+ synthesized without β-CD, pure β-CD and physical mixture of *PANI-P(AAm- co -AA)@Fe 3+ together with β-CD (the mass ratio is 1 : 1) were performed. 53 As shown in Fig. S12a (ESI†), the blunt peaks of β-CD at ∼3380 cm −1 and ∼1034 cm −1 are attributed to the stretching vibration and bending vibration of O–H.…”

“…However, the peak of *PANI-P(AAm- co -AA)@Fe 3+ is sharper and higher than that of PANI-P(AAm- co -AA)@Fe 3+ . The reason is that non-covalent interaction in the inclusion complex decreases the energy of PANI and reduces its peak intensity, 53 which can verify the host–guest interaction between β-CD and PANI. Fig.…”

Thermo/pH dual-responsive micelles based on the host–guest interaction between benzimidazole-terminated graft copolymer and β-cyclodextrin-functionalized star block copolymer for smart drug delivery

“…Further investigation into the successful association of BM units and CD units was conducted using FT-IR spectroscopy and AFM as complementary methods. FT-IR spectroscopy is an excellent analytical tool to confirm the formation of inclusion complexes via noncovalent interaction between host and guest molecules by identifying considerable changes in intensity, characteristic peak position, and shape [ 38 , 49 , 50 ]. FTIR spectra were firstly utilized to evidence the formation of graft copolymer micelles via host–guest interactions.…”

Supramolecular recognition enhanced electrochemical sensing: β-cyclodextrin and Pd nanoparticle co-decorated 3D reduced graphene oxide nanocomposite-modified glassy carbon electrode for the quantification of ractopamine

“…Keeping the total molar concentrations of the host (β-CD) and the guest (RAC) at constant values, a series of solution mixtures (RAC and β-CD) with different molar concentration ratios between 0 and 1 were prepared, and the UV-vis absorbance values of pure RAC and the mixed solutions were measured at 273 nm. 33…”

“…Keeping the total molar concentrations of the host (b-CD) and the guest (RAC) at constant values, a series of solution mixtures (RAC and b-CD) with different molar concentration ratios between 0 and 1 were prepared, and the UV-vis absorbance values of pure RAC and the mixed solutions were measured at 273 nm. 33 1 H NMR spectrum determination of b-CD and RAC. b-CD, RAC, and their aggregates were dissolved in D 2 O and NMR hydrogen spectra were recorded using an Ascend 400 MRI.…”
