Three Sonogashira-Hagihara polymerization protocols were applied for the synthesis of conjugated microporous polymers (CMPs) by using groupIV 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 decreasedindependently from the chosen parameters of catalyst, base, and solventfrom carbon-centered CMPs (1595m(2)g(-1)) to silicon-, germanium-, and tin-centered (649m(2)g(-1)) networks.
