标题:一种高效,可靠的高反应性立克锌的制备方法
摘要:Rieke锌在有机化学中具有广泛的应用潜力,特别是在高度化学选择性的有机锌试剂的合成中.但是,由于制备方法相当不可靠,导致批次间差异很大,因此其使用受到了很大的限制.Rieke锌通常是通过使用化学计量的萘将锂与氯化锌还原而制得的.在我们手中,观测到反应的结果高度依赖于萘的来源和纯度等级.苯并噻吩的存在似乎对于避免锌颗粒的凝结至关重要,并且苯并噻吩的量对所得锌粉的物理性质和反应性具有很大的影响.因此,2)将苯并噻吩放入萘锂溶液(原位制备)中.以这种方式获得的rieke锌被成功地用于所谓的" Rieke方法"中以制备区域规则的聚(3-己基噻吩)(p3Ht).该新颖方法使得能够以可再现的方式制备rieke锌,这极大地促进了其在小分子和聚合物合成中的使用.

标题:Living synthesis of conducting polymers including regioregular polymers, polythiophenes, and block copolymers

摘要:Regioregular poly(3-alkylthiophenes) and other polythiophenes can be prepared by living polymerization which have good solubility, processability and environmental stability. The polymerization method can afford regioregular poly(3-alkylthiophenes) in high yields. Kinetic study of polymerization revealed the living character of this process. The molecular weight of poly(3-alkylthiophenes) is a function of the molar ratio of the monomer to nickel initiator, and conducting polymers with relatively narrow molecular weight distribution (PDI<1.5) are now readily available. Sequential monomer addition resulted in new block copolymers containing different poly(3-alkylthiophene) segments, which further confirms the “livingnessâ€? of this system. Other synthetic methods can be used as well to conduct living polymerization. Blends and electronic devices can be prepared.

摘要:The invention relates to the synthesis of polythiophene (PAT) copolymers, and their use as conductive polymers in final applications. Specifically, copolymers of PAT with (meth)acrylates, or amides are useful as additives in blends of different polymer matrices in many commercial applications.
