Abstract
Crystalline and amorphous organic materials are an emergent class of heterogeneous photocatalysts for the generation of hydrogen from water, but a direct correlation between their structures and the resulting properties has not been achieved so far. To make a meaningful comparison between structurally different, yet chemically similar porous polymers, two porous polymorphs of a triazine-based graphdiyne (TzG) framework are synthesized by a simple, one-pot homocoupling polymerization reaction using as catalysts CuI for TzGCu and PdII /CuI for TzGPd/Cu . The polymers form through irreversible coupling reactions and give rise to a crystalline (TzGCu ) and an amorph...
