Abstract

The synthesis of triptycene-based three-dimensional networks and their uptake towards various gases are described. The target polymers TPP1-3 were synthesized by employing a convenient palladium-catalyzed Suzuki-Miyaura cross-coupling reaction between a triptycene synthon bearing two peripheral dibromotetraphenyl benzene (TBT) units and various arylboronic acid/ester moieties. Polymers TPP1-3 were characterized by several instrumental analysis techniques, namely, solid-state ¹³C nuclear magnetic resonance (SSNMR), thermogravimetric analysis (TGA), Fourier transform infrared (FTIR), and emission spectrophotometry. Brunauer-Emmett-Teller (BET) nitrogen adsorption investigation of TPP1-3 revealed surface areas up to 468 m² g⁻¹ and an average pore volume of ~0.25 cm³ g⁻¹. Interestingly, low-pressure gas adsorption studies of TPP1-3 disclosed a CO₂ uptake for TPP1 of 78.4 mg g⁻¹ (273 K) and a gas adsorption capacity for TPP2 towards H₂ and CH₄ of 10 mg g⁻¹ (77 K) and 7.9 mg g⁻¹ (273 K), respectively.
