  A Novel Approach to the Molecular Imprinting of Polychlorinated Aromatic Compounds

  摘要：

  The aim of this investigation was to determine whether relatively weak interactions, such as hydrogen bonds to aromatic chlorine atoms and interactions involving aromatic pi electrons could be exploited within artificial receptors, constructed using the technique of molecular imprinting. For the purposes of this investigation we chose 2,3,7,8-tetrachlorodibenzodioxin (TCDD)as the model target. Imprinted polymers have been prepared with two new templates designed to create recognition sites for TCDD. The first of these, the bis-N-(4-vinylphenyl)urea derivative of 2,8-dichloro-3,7-diaminodibenzodioxin, employed a carbonyl spacer to introduce aromatic amines into the polymer after reductive cleavage of the template. The second, N-(2-(3,7,8-trichlorodibenzodioxinyl))-2-methacryloyloxybenzamide, incorporated a salicylic acid spacer and introduced a methacrylic acid residue into the polymer following hydrolysis. Both amine and acid groups were positioned in such a way as to interact with TCDD through the formation of weak hydrogen bonds to aromatic chlorine atoms. A second recognition element was introduced into the binding sites by the inclusion of a polymerizable, electron-rich, aromatic ether capable of forming pi-pi interactions with the electron-deficient dioxin molecule. Polymers imprinted with either template showed significantly higher uptake of TCDD than the corresponding nonimprinted controls, even at concentrations as low as 2 nM.

  An object of the present invention is to provide a paste-type cement composition which while retaining adhesion to tooth substance, biocompatibility, surface curability and fluorine sustained-releasability which are the characteristics derived from the conventional glass ionomer cement, reduces water sensitivity which is shortcoming of the conventional glass ionomer cement, enables simple mixing operation, does not adversely affect on the various properties of a cured cement depending on a difference in operators or a skill degree, and can afford various stable properties. There is provided a two paste-type glass ionomer cement comprising a resin-based paste containing a hydrophobic polymerizable monomer and a polymer of acidic group-containing polymerizable monomers which are insoluble to each other, and a water-based paste containing a hydrophilic polymerizable monomer and water which are soluble to each other, in which an acid reactive filler is contained in at least one of pastes.

  Novel stress-reducing crosslinking oligomers that have application in dental restoratives, thin films, hardcoats, composites, adhesives, and other uses subject to stress reduction are described. The addition-fragmentation process of crosslinking results in a chain-transfer event that provides novel polymers that may be further functionalized. In addition, the addition-fragmentation oligomer comprises pendent functional groups that bond to a substrate by forming an ionic or covalent bond, or etch the substrate by chemically removing some material from the substrate.
