Three Sonogashira-Hagihara polymerization protocols were applied for the synthesis of conjugated microporous polymers (CMPs) by using group IV tetra(p-ethynylphenyl) monomers with 1,4-diiodobenzene or 1,4-dibromobenzene. The optical properties and surface areas of the CMPs were compared and related to the preparation conditions and the geometry of the tetrahedral building block as obtained after X-ray analysis. In each series, surface areas decreased-independently from the chosen parameters of catalyst, base, and solvent-from carbon-centered CMPs (1595 m2  g-1 ) to silicon-, germanium-, and tin-centered (649 m2  g-1 ) networks.

微孔聚合物中的四面体四（对-乙炔基苯基）IV族化合物：蝶粉对孔隙率的影响。

通过使用IV组四（对乙炔基苯基）单体与1,4-二碘苯或1,4-二溴苯，将三种Sonogashira-Hagihara聚合规程用于合成共轭微孔聚合物（CMP）。比较了CMP的光学性质和表面积，并将其与X射线分析后获得的制备条件和四面体结构单元的几何形状相关。在每个系列中，表面积均从以碳为中心的CMP（1595 m2 g-1）变为以硅，锗和锡为中心的（649 m2 g-1），而与催化剂，碱和溶剂的所选参数无关。 ）网络。
