  "description": "<p>Structural modularity of polymer frameworks is a key advantage of covalent organic polymers, however, only C, N, O, Si and S have found their way into their building blocks so far. Here, we expand the toolbox available to polymer and materials chemists by one additional nonmetal, phosphorus. Starting with a building block that contains a &lambda;<sup>5</sup>-phosphinine (C<sub>5</sub>P) moiety, we evaluate a number of polymerisation protocols, finally obtaining a &pi;-conjugated, covalent phosphinine-based framework (CPF-1) <em>via</em> Suzuki-Miyaura coupling. CPF-1 is a weakly porous polymer glass (72.4&nbsp;m<sup>2</sup>&nbsp;g<sup>-1</sup> N<sub>2</sub> BET at 77&nbsp;K) with green fluorescence (&lambda;<sub>max</sub> 546&nbsp;nm) and extremely high thermal stability. The polymer catalyzes hydrogen evolution from water under UV and visible light irradiation without the need for additional co-catalyst at a rate of 33.3&nbsp;&mu;mol&nbsp;h<sup>-1</sup>&nbsp;g<sup>-1</sup>. Our results demonstrate for the first time the incorporation of the phosphinine motif into a complex polymer framework. Phosphinine-based frameworks show promising electronic and optical properties that might spark future interest in their applications in light-emitting devices and heterogeneous catalysis.</p>",
