“…3A. Strong absorption bands at around 3432, 2930 and 1700 cm −1 were observed, which could be attributed to the stretching vibration of C O, C H and O H in MAA [22]. Absorption bands at around 1600 and 1450 cm −1 were observed due to C C stretching vibration in benzene ring of DVB or MAA [23].…”

a b s t r a c tNovel multi-template molecularly imprinted polymers (mt-MIPs) with six phenolic compounds as the template, namely phenol, 4-chlorophenol (4-CP), 2,4,6-trichlorophenol (2,4,6-TCP), 2,4-dichlorophenol (2,4-DCP), 2-chlorophenol (2-CP) and 2,6-dichlorophenol (2,6-DCP), were prepared by precipitation polymerization and used as the adsorbents of solid-phase extraction (SPE), and coupled with capillary electrophoresis (CE) for the simultaneous selective extraction, separation and determination of trace phenolic compounds in water samples. The resultant mt-MIPs exhibited uniform spherical morphology, large specific surface area and high thermal stability, and offered high selectivity towards the six template phenolic compounds. Various parameters affecting the molecularly imprinted SPE (MISPE) efficiency were investigated in detail, and excellent CE separation was realized within 7 min. Good linearity was obtained in the range of 1-200 g L −1 for phenol and 4-CP, and 1-300 g L −1 for 2,4,6-TCP, 2,4-DCP, 2-CP and 2,6-DCP. High sensitivity was attained with low limits of detection and quantification ranging from 0.17 to 0.31 g L −1 and 0.57 to 1.03 g L −1 , respectively. Satisfactory recoveries for spiked reservoir water, river water, tannery wastewater and tap water samples were achieved in the range of 82.13-105.63% with relative standard deviations within 1.68-6.96%. The developed MISPE-CE method proved practically feasible for simultaneous selective extraction/enrichment, separation and sensitive determination of multiple targets in complicated aqueous matrices.

“…[ 30 ] The binding ability of the MIP was superior to NIP owning to the supramolecularly imprinted hydrogen bonding interactions. Surikumaran and coworkers [ 31 ] linked MAA and β‐CD via toluene‐2,4‐diisocyanate (TDI) to prepare MAA‐TDI‐β‐CD as the functional monomer. The MAA‐TDI‐β‐CD MIP had a stronger binding ability to 2,4‐dichlorophenol (2,4‐DCP) in water samples than that of MAA‐MIP due to the triple interaction between MAA‐TDI‐β‐CD and 2,4‐DCP (hydrogen bonding, π–π interaction, and host–guest inclusion), whereas there were only hydrogen bonds between MAA and 2,4‐DCP without specificity.…”

Molecular imprinting polymers (MIPs), generally considered as artificial mimics that are comparable to natural receptor, are polymers with tailor‐made specific recognition sites complementary to the template molecules in shape and size. As a class of supramolecular compounds, cyclodextrins (CDs) are flourishing in the field of molecular imprinting with their unique structural properties. This review presents recent advances in application of MIPs based on CDs during the past five years. The discussion is grouped according to the different role of CDs in MIPs, that is, functional monomer, carrier modifier, etc. Main focus is the application of CD‐based MIP on sample preparation, detection, and sensing. Additionally, drug delivery with CD‐based MIP is also briefly discussed. Finally, challenges and future prospects of application of CDs in MIP are elaborated.

“…This is maybe because the phenols were retained on the NIP MAA-βCD by physical adsorption, and thus they were easily eluted in the washing step (15). The binding force between MIP MAA-βCD and the phenols in this study was mainly due to the inclusion complex formation between β-CD cavity and phenols and π-π interaction (between double bond of MAA in polymer network and π-electron from benzene ring of phenol compounds) besides the presence of imprinted cavities (38,40). This explains well the highest recoveries obtained for phenol compounds when MIP MAA-βCD was employed as the SPE material in this study.…”

“…The synthesis of MAA-βCD monomer was performed first according to some literature with slight modification (32,39) and then followed by synthesis of imprinted polymers which was reported in our previous works (38,40). First, the template molecule, 2,4-DCP (0.14 mmol) was dissolved in 60 mL DMAC in a flask.…”

Molecularly imprinted polymer (MIP MAA-βCD) with 2,4-dichlorophenol (2,4-DCP) and methacrylic acid functionalized β-Cyclodextrin (MAA-βCD) as the template molecule and the functional monomer respectively, was prepared and used in molecular imprinted-solid phase extraction (MISPE) for the extraction of phenols (2,4-dichlorophenol, 2-chlorophenol, 4-chloro-3-methylphenol, 4-chlorophenol, 2,4,6-trichlorophenol and 2-nitrophenol) from water samples.The MISPE method was optimized prior to the determination using gas chromatography coupled with a flame ionization detector (GC-FID). Under the optimized conditions, the MIP MAA-βCD sorbent showed good linearity (0.01-12 mgL -1 ), low limits of detection (0.14-0.75 µgL -1 ) and good repeatability (RSD 2.3-3.6%, n =3). Good recoveries were obtained in the range of 97- Separation Science and TechnologyA c c e p t e d M a n u s c r i p t 2 115% for tap water and between 88-103% for river water. The developed MIP MAA-βCD SPE was then compared with other adsorbents. The unique properties of β-CD and presence of imprinted cavities explains the higher extraction recoveries obtained for phenols when using MIP MAA-βCD SPE.
