6-bis(4-chlorocarbonyl-2-oxabutyl)-4,8-dioxaundecane-1,11-dicarbonyl chloride. These new constructs were fully characterized, shown to exhibit good solubilities in organic as well as aqueous solvents, and demonstrated to solubilize lithium triflate salts in nonaqueous environments, such as chloroform.
树枝状聚合物最多三个世代,所述分支框架内具有内部PEG单元,通过经由基于胺的树枝状大分子的反应的会聚合成的方法6,9,和11与6,6-双(4-氯羰基- 2-氧杂丁基) -4,8-二氧杂十二烷-1,11-二羰基氯。这些新的构建体已得到充分表征,显示在有机和水性溶剂中均显示出良好的溶解性,并在非水环境(如氯仿)中溶解了三氟甲磺酸锂盐。
