摘要:
The present invention refers to new classes of polymerisable monomers, to molecularly imprinted polymers obtainable by polymerisation of at least one of the monomers and a crosslinking monomer in the presence of a template molecule. The obtained polymers may be used for separation of enantiomers, diastereomers of the template molecule, and also for separation of the template molecule or template molecule analogues from structurally related compounds.

摘要:
A method of producing a molecularly-imprinted material comprises synthesizing a peptide, oligosaccharide or oligonucleotide on a disposable surface modified support to produce a support surface-attached peptide, oligosaccharide or oligonucleotide, providing a selected monomer mixture, contacting the monomer mixture with the support surface-attached peptide, oligosaccharide or oligonucleotide, initiating polymerisation or at least one crosslinking reaction, dissolving or degrading the support surface-attached peptide, oligosaccharide or oligonucleotide and support, and obtaining molecularly imprinted material.
摘要:
A porous, molecularly imprinted polymer and a process for its preparation are described. The porous, molecularly imprinted polymer is characterised in that it is obtainable by providing a porous silica; attaching a molecular template to the surface of the porous silica; filling the pores of the porous silica with a polymer, removing the silica and the molecular template, thereby leaving a porous, molecularly imprinted polymer. The process is characterised by the above defined process steps. Also described are a porous polymer vesicle and its preparation with the same features as defined for the porous, molecularly imprinted polymer and its preparation, except for the lack of the molecular template and thus the lack of the molecular imprint in the porous polymer.

The invention refers to a molecularly imprinted polymer, a method of preparing a molecularly imprinted polymer material, and the use thereof. According to the invention a support comprising at least one monomer, and a template, in a polymerization medium is polymerized with a free radical initiator, whereafter the template is removed from the molecularly imprinted polymer obtained. The polymerization is confined to the surface of the support, preferably by confining the free radical initiator to the support by bonding adsorption. The molecularly imprinted polymer may be used in chromatography, for separations, in chemical sensors, in molecular recognition as stationary phase in capillaries, in selected sample enrichment or in catalysis.
摘要:
A surface coating and its use in chemical analysis, electronics, and optoelectronics is disclosed. The surface coating is characterized in that it comprises an amphiphile reversibly bound to a substrate by non-covalent interaction, preferably by polar interaction. The amphiphile is a bolaamphiphile, such as pentamidine.
摘要:
The invention relates to a polymer obtainable by radical co-polymerization of a first monomer of general formula (I) or (II) or a mixture thereof: wherein A, A′, B, B′ X, Y, Y′ and n are as defined herein; with a second, cross-linking monomer and optionally with one or more further co-monomers; wherein the molar ratio of the first monomer to other monomers is less than or equal to 1:5. The polymers selectively bind to phosphate ester compounds and can be used as a solid phase in a method for isolating compounds comprising a phosphate ester group from a mixture comprising one or more phosphate monoesters and/or phosphate diesters and/or other compounds such as lipids.
摘要:
A class of molecularly imprinted polymers that specifically recognizes and binds to nitrosamines members of which class are useful, for example, in analysis and separation of nitrosamines from biological fluids. Such molecularly imprinted polymers are also useful in methods of treating and manufacturing tobacco products and materials.
