Synthesis of a microporous biphenylene-pillared ilerite using 4,4'-Bis(methyldichlorosilyl)biphenyl

Abstract

We report a synthesis of the microporous nanocomposite using a biphenylene-bridged chlorosilane, which contains methyldichlorosilyl groups at each end of the unit. The product shows sharper (00l) reflections than those of the nanocomposite using the alkoxysilane compound, indicating the improvement of the structural order of the stacking. The basal spacing is calculated as ca. 2.9 nm. The large basal spacing suggests that the biphenylene units form a double-layer arrangement in the interlayer.
