Chiral separation of (±)-methamphetamine racemate using molecularly imprinted sulfonic acid functionalized resin

Interaction of LiYF4:Yb3+/Er3+/Ho3+/Tm3+@LiYF4:Yb3+ upconversion nanoparticles, molecularly imprinted polymers, and templates

“…Molecular imprinting is a powerful method for the preparation of polymeric materials with tailor-made molecular recognition binding sites that have been used in applications such as chemical separations, catalysis, or molecular sensors. [1][2][3] The in situ polymerization of molecularly imprinted polymers (MIPs) is based on the copolymerization of the template and functional monomers through covalent/non-covalent interactions with crosslinkers. 4,5 Aer polymerization, these materials retain special cavities with corresponding steric and chemical memories upon the removal of the template.…”

Chiral Stationary Phases for Liquid Chromatography: Recent Developments

“…The most recent developments comprised the adaptation of this type of CSP to monoliths, nanoparticles, and predominantly to polymers. The introduction of different supports such as alginate microspheres [254] or polymer functionalized with quantum dots [255] were also reported as well as the description of different functional monomers and crosslinking agents [256,257,258,259].…”

Sample Preparation Using Molecularly Imprinted Polymers

“…47 This was also achieved by synthesizing a polymerizable template, a phenolic R-amphetamine sulfonamide derivative, that was combined with phenol and formaldehyde, the sulfonamide linkage being further hydrolyzed to provide cavities for the trapping of R-amphetamine. 40 Boronic acid was also used for its ability to form a reversible covalent complex with cis-diol compounds such as luteolin, 48,49 vitamin B12, 50 sialic acid, 51 or for the specific trapping of glycans of glycoproteins as discussed in more detail below. Many works reported the screening of different synthesis conditions by preparing MIPs using different types of monomers, cross-linkers, template/monomer or monomer/cross-linker ratios, natures of the porogen, 28,30,39,43,[52][53][54][55][56][57][58][59][60][61][62][63][64][65] and even the pH when boronic acid is involved.…”
