标题:芳基咪唑并菲啰啉荧光染料的合成及对金属离子的识别
摘要:本发明公开一种芳基咪唑并菲啰啉荧光染料的合成及对金属离子的识别.它能以廉价易得的1,10‑菲啰啉为原料通过一系列步骤合成芳基咪唑并[4,5‑f]菲啰啉类氧杂冠醚类化合物的方法.通过对芳基咪唑并[4,5‑f]菲啰啉类化合物的荧光性能进行筛选,通过对不同金属离子的筛选实验,以及对离子浓度等实验来验证化合物的与金属离子的络合性能,实现对肿瘤细胞中金属离子zn2+的识别.本发明的荧光探针技术效果如下:1,化合物在广泛的金属离子上分别显示出对zn2+的高选择性;2,可在mcf‑7细胞中实现对zn2+响应的荧光淬灭分子开关,这为该体系应用于生物识别等更多领域起到了较大的铺垫作用.

标 题 :Synthesis of silyl-functional telechelic hydrocarbon polymers
发明人：ROY AROOP K
权利人:DOW CORNING
摘要:A method for preparing a telechelic polydiene having at least 70% 1,4-microstructure and at least 70% of its end groups capped by reactive silyl functionality is disclosed, said method comprising: n (I) reacting, in a non-polar solvent solution, n (A) at least one diene monomer, n (B) a dianionic initiator which is soluble in said non-polar solvent and, optionally, n (C) a polymerization adjuvant to form a dianionically active polydiene; and n (II) capping both ends of said dianionically active polydiene from step (I) with n (D) a silane, said capping being carried out in the presence of n (E) a promoter selected from the group consisting of a tertiary amine and a crown ether based on 12-crown-4.
