Tetrahedral Tetrakis(p-ethynylphenyl) Group IV Compounds in Microporous Polymers : Effect of Tetrel on Porosity
© 2018 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim..
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.
