离子液体(ILs)的独特性能使其成为电化学应用的有希望的候选者。相应IL的聚合产生了一类称为聚合离子液体(PolyIL)的新型材料。尽管PolyIL提供了将IL的高电导率和聚合物的高机械强度相结合的可能性,但它们的电导率通常远低于相应的小分子IL的电导率。在本工作中,合成了七个聚合度为1至333的PolyIL,对应的分子量(MW)为482至160 400 g / mol。去极化动态光散射,宽带介电谱,流变学,差示扫描量热法和差示扫描量热法被用来系统地研究MW对这些材料中离子迁移和分段动力学的影响。修改后的Walden图分析显示,随着MW的增加,离子电导率从与结构弛豫紧密耦合转变为与离子强分离。

The present invention relates to a cationic lipid having one or more biodegradable groups located in a lipidic moiety (e.g., a hydrophobic chain) of the cationic lipid. These cationic lipids may be incorporated into a lipid particle for delivering an active agent, such as a nucleic acid. The invention also relates to lipid particles comprising a neutral lipid, a lipid capable of reducing aggregation, a cationic lipid of the present invention, and optionally, a sterol. The lipid particle may further include a therapeutic agent such as a nucleic acid.

tautomerizes to saturated esters, while the P–O bond cleavage by HBpin via a formal σ-bond metathesis affords boryl enolate intermediate. The latter could undergo a further coupling reaction with nitriles to form substituted amino diesters or 1,3-imino esters, depending on α,β-unsaturatedester substrates. These catalytic reactions can also be performed in a one-pot manner, illustrating a protocol for metal-free
