ABSTRACT=<p>A set of five nanoporous (pore size &lt;100 nm) amine-functionalized and triptycene-based organic polymers (<bold>TBPALs</bold>) 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<sup>II</sup> or CuI. TBPALs demonstrated their ability to reversibly capture small gas molecules such as CO<sub>2</sub>, H<sub>2</sub>, CH<sub>4</sub>, and H<sub>2</sub>. Highest uptake of CO<sub>2</sub> and H<sub>2</sub> was observed for <bold>TBPAL2</bold> at 163.7 mg g<sup>−1</sup> (273 K) and 16.2 mg g<sup>−1</sup> (77 K), respectively.</p>
