Rational Construction of an Extrinsic Porous Molecular Crystal with an Extraordinary High Specific Surface Area

Abstract

Small molecule, large surface area: A rigid triptycene derivative self-assembles by hydrogen bonds to a porous crystal with one-dimensional channels of about 14 Å diameter. Solvents in the channels can be removed to generate an extrinsic porous material with a specific BET surface area of 2796 m2 g−1. Furthermore, gases can be selectively adsorbed within the pores at 1 bar. Detailed facts of importance to specialist readers are published as ”Supporting Information”.
