Abstract

A set of five nanoporous (pore size <100 nm) amine-functionalized and triptycene-based organic polymers (TBPALs) were prepared using commercially available phenols (such as quinol and phloroglucinol) and triptycene amines. C–N bonds were formed in the polymerization reactions without employing transitional metal catalysts such as Pd^II or CuI. TBPALs demonstrated their ability to reversibly capture small gas molecules such as CO₂, H₂, CH₄, and H₂. Highest uptake of CO₂ and H₂ was observed for TBPAL2 at 163.7 mg g⁻¹ (273 K) and 16.2 mg g⁻¹ (77 K), respectively.
