Abstract

Abstract: An expanded triptycene (hexaphenylbenzene based triptycene) monomer was synthesized from triiodotriptycene. Using this monomer, two kinds of organic microporous polymersHTP s (HTP-A andHTP-B ) were prepared by Friedel–Crafts and Scholl reactions. Their structure and properties were characterized by FT-IR, solid 13 C NMR, powder XRD, SEM, TEM and gas absorption. Nitrogen sorption analysis displayed that the BET surface areas are 569 and 914 m 2 g −1 forHTP-A andHTP-B, respectively. ForHTP-B, they can reversibly absorb 1.09 wt % H2 (1.0 bar and 77 K) and 10.3 wt% CO2 (1.0 bar and 273 K), respectively. Graphical abstract: Highlights: Hexaphenylbenzene based triptycenes were used as monomer to synthesizeHTP s. Two low-cost Friedel–Crafts and Scholl reactions were used to synthesize HTPs. HTP-B displays high CO2 uptake capacity of 10.3 wt %.
