在这里，我们表明，非网络金属聚合物可以具有固有的微孔性源于金属茂结构单元引入的扭曲。合成了由苯基联乙炔桥连接的二茂铁基结构单元构成的金属聚合物，其BET表面积高达400 m2 g−1。由于侧基赋予的溶解度降低了孔隙率，因此共聚用于同时改善可及表面积和溶解度。光谱分析提供的证据表明，在这些聚合物中支持相邻的二茂铁基单元之间的混合价。
We show here that non-network metallopolymers can possess intrinsic microporosity stemming from contortion introduced by metallocene building blocks. Metallopolymers constructed from ferrocenyl building blocks linked by phenyldiacetylene bridges are synthesized and possess BET surface areas up to 400 m2 g−1. As solubility imparted by pendant groups reduces porosity, copolymerization is used to simultaneously improve both accessible surface area and solubility. Spectroscopic analysis provides evidence that mixed valency between neighboring ferrocenyl units is supported in these polymers.
