在过去的几十年里，无机聚合物的合成一直是一个巨大的合成挑战。尽管无机化学的相对有限的变化和实用性阻碍了由外来键组成的各种稳定的无机聚合物的容易合成，但迄今报道的此类材料被发现具有独特的特性，例如低温柔性、高热或氧化稳定性、不燃性以及独特的电学和光学性质。鉴于有机硼化合物在发光材料、NLO材料、阴离子传感器、离子传导材料等方面的应用，有机硼化合物目前正吸引着越来越多的兴趣。2-4 Chujo等人的开创性工作表明，某些有机硼聚合物3足够稳定，可以用作新型功能材料。我们已经将这种方法扩展到制备定义明确的有机硼聚合物电解质4，其通过硼原子的阴离子捕获效应显示出选择性离子传输性能。本工作以均三甲苯硼氢化锂和低聚环氧乙烷为原料，通过脱氢偶联聚合，
Synthesis of inorganic polymers1 has been a great deal of synthetic challenge for the past several decades. Even though relatively limited variation and utility of inorganic chemistry have prevented the facile synthesis of a variety of stable inorganic polymers composed of exotic bondings, such materials reported to date were found to possess unique characteristics such as low-temperature flexibility, high thermal or oxidative stability, nonflammability and unique electrical and optical properties.Recently, as a new class of inorganic materials, organoboron compounds are attracting growing interest these days in view of application for light emitting materials, NLO materials, anion sensor, ion conductive materials, etc. 2-4 The pioneering work by Chujo et al. demonstrated that some organoboron polymers3 are sufficiently stable to serve as a novel type of functional materials. We have extended such method for the preparation of well-defined organoboron polymer electrolytes4 which showed selective ion transporting property via anion trapping effect of the boron atom. In the present work, as a new class of organoboron polymer, poly (lithium organoborate) s were prepared by dehydrocoupling polymerization between lithium mesitylhydroborate and oligo (ethylene oxide) and subsequent
