摘要:在一种独特的方法中,羟基石墨烯量子点 (Gqds-Oh) 的供体-受体对和具有吡啶单元 ( Bpbp ) 的红色发射供体-双受体 (D-2-A) 型染料的组合以及基于亲和力驱动的客体交换,众所周知的宿主葫芦[7]脲(cb[7])已被用作超分子传感组件,用于检测亚ppb级水介质中的癌症生物标志物精胺和亚精胺来自 Cb[7] 门户.在二元偶联物中,绿色荧光 Gqds-Oh 转移能量以触发染料bpbp的发射并且本身保持在关断状态.Cb[7] 通过与其门户的强烈主客体相互作用从 Gqds-Oh 表面撤除染料,使 Gqds-Oh 再次发出荧光以产生比率响应.在精胺 (Sp) 或亚精胺 (Spd) 存在的情况下,它们与 Cb[7] 的强亲和力迫使荧光团喷射到 Gqds-Oh 表面,并且 Gqds-Oh 的强绿色发射关闭到设备用于检测 Sp/spd 的超分子传感器.Dft 研究揭示了bpbp之间有趣的激发态电荷转移共轭形成和

标 题 :Purification methods for large scale synthesis of cucurbit[7]uril-peg conjugates
发明人：WEBBER MATTHEW J
权利人:PORTAL INSULIN LLC
摘要:Methods of purification for the large scale synthesis of CB[ 7 ]-PEG may include at least one of diafiltration or tangential flow filtration, column chromatography, affinity “pull-downâ€? techniques, or selective precipitation methods. In one embodiment, the method includes providing a reaction mixture containing synthesized CB[ 7 ]-PEG, providing a membrane selected to be below the nominal molecular weight of CB[ 7 ]-PEG, and removing small molecular weight contaminant species from the reaction mixture using the membrane. In embodiments, regardless of which purification method is used, a copper catalyst component of the “clickâ€? chemistry reaction mixture may be removed using a commercially available metal-chelating resin.

摘要:A styrene based water soluble polymer containing pendant sulfonated calix[4]arene groups has been synthesized by using free radical polymerization combined with post-polymerization sulfonation chemistry. The monomer 25-(4-vinylbenzyl)-26, 27, 28-hydroxy-calix[4]arene was prepared in 3 steps: (1) reduction of 4-vinyl benzoic acid to the respective alcohol (2) formation of the bromide by the Appel reaction and (3) synthesis of the respective ether by Williamson O-alkylation reaction with calix[4]arene. Polymerization was accomplished by azobisisobutyronitrile (AIBN) initiated free radical polymerization technique. Electro-responsive properties of the sulfonated polymer were studied wherein a response to electrochemical stimulus is observed when guest molecules of methyl viologen are incorporated with polymerized 25-(4-vinylbenzyl)-26, 27, 28-hydroxy-calix[4]arene.

摘要:A method for producing cucurbit[n]urils, where n is from 4 to 12, comprising mixing substituted and/or unsubstituted glycoluril with an acid and a compound that can form methylene bridges between glycoluril units, and heating the mixture to a temperature of from 20° to 120° to thereby form cucurbit[n]. Novel cucurbit[n]urils, where n=4, 5, 7, 8, 9, 10, 11 and 12 and substituted cucurbit[s,u]urils, where s=number of substituted glycoluril units, u=number of unsubstituted units and s+u=4-12 are also described.
