Herein we present a rational strategy for the development of nitrogen-enriched conjugated microporous polymers (CMPs) (TBTT-CMP@1, 2 and 3) via a BH coupling reaction under mild conditions, for the super absorption of iodine. TBTT-CMP@1 exhibited iodine capture amount up to 442 wt%.

<p>Three series of conjugated microporous polymers (CMPs) were studied as photocatalysts for producing hydrogen from water using a sacrificial hole-scavenger. In all cases, dibenzo[<i>b</i>,<i>d</i>]thiophene sulfone polymers outperformed their fluorene analogs. A porous network, S-CMP3, showed the highest hydrogen evolution rate of 6076 µmol h<sup>-1</sup> g<sup>-1</sup> (λ > 295 nm) and 3106 µmol h<sup>-1</sup> g<sup>-1</sup> (λ > 420 nm), with an external quantum efficiency of 13.2% at 420 nm. S-CMP3 outperforms its linear structural analog, P35, while in other cases, non-porous linear polymers are superior to equivalent porous networks. This suggests that microporosity can be beneficial for sacrificial photocatalytic hydrogen evolution, but not for all monomer combinations.</p>
