rdf:resource="https://doi.org/10.1002/cssc.201802034"/> <dct:description><p>Crystalline and amorphous organic materials are an<br> emergent class of heterogeneous photocatalysts for the generation of<br> hydrogen from water, but a direct correlation between their structures<br> and the resulting properties has not been achieved so far. To make a<br> meaningful comparison between structurally different, yet chemically<br> similar porous polymers, we present two porous polymorphs of a<br> triazine-based graphdiyene (TzG) framework from a simple, one-pot<br> reaction using Cu(I) for TzG<sub>Cu</sub> and Pd(II)/Cu(I) for TzG<sub>Pd/Cu</sub> catalyzed<br> homocoupling polymerization. The polymers form via irreversible<br> coupling reactions and give rise to a crystalline (TzG<sub>Cu</sub>) and an<br> amorphous (TzG<sub>Pd/Cu</sub>) polymorph. Notably, the crystalline and<br> amorphous polymorphs are narrow-gap semiconductors with<br> permanent surface areas of 660 m<sup>2</sup> g<sup>-1</sup> and 392 m<sup>2</sup> g<sup>-1</sup>, respectively.<br> Hence, both polymers are ideal heterogeneous photocatalysts for<br> water splitting with some of the highest hydrogen evolution rates<br> reported thus far up to 972 &mu;mol h<sup>-1</sup> g<sup>-1</sup> with and 276 &mu;mol h<sup>-1</sup> g<sup>-1</sup><br> without Pt co-catalyst. We conclude, that crystalline order improves<br> delocalisation, while the amorphous polymorph requires a co-catalyst<br> for efficient charge transfer; this will need to be considered in future<br> rational design of polymer catalysts and organic electronics.</p></dct:description> <dct:accessRights rdf:resource="http://publications.europa.eu/resource/authority/access-right/PUBLIC"/> <dct:accessRights> <dct:RightsStatement rdf:about="info:eu-repo/semantics/openAccess"> <rdfs:label>Open Access</rdfs:label> </dct:RightsStatement> </dct:accessRights> <dcat:distribution> <dcat:Distribution> <dct:license rdf:resource="https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode"/> <dcat:accessURL rdf:resource="https://zenodo.org/record/1471618"/> </dcat:Distribution> </dcat:distribution> <dcat:distribution> <dcat:Distribution> <dcat:accessURL>https://doi.org/10.1002/cssc.201802034</dcat:accessURL> <dcat:byteSize>1012588</dcat:byteSize> <dcat:downloadURL>https://zenodo.org/record/1471618/files/20180904_TzG_OA.pdf</dcat:downloadURL> <dcat:mediaType>application/pdf</dcat:mediaType> </dcat:Distribution> </dcat:distribution> <dcat:distribution> <dcat:Distribution> <dcat:accessURL>https://doi.org/10.1002/cssc.201802034</dcat:accessURL> <dcat:byteSize>2435260</dcat:byteSize> <dcat:downloadURL>https://zenodo.org/record/1471618/files/20180904_TzG_SI_OA.pdf</dcat:downloadURL> <dcat:mediaType>application/pdf</dcat:mediaType> </dcat:Distribution> </dcat:distribution> </rdf:Description> <foaf:Project rdf:about="info:eu-repo/grantAgreement/EC/H2020/678462/"> <dct:identifier rdf:datatype="http://www.w3.org/2001/XMLSchema#string">678462</dct:identifier> <dct:title>Layered functional materials - beyond 'graphene'</dct:title> <frapo:isAwardedBy> <foaf:Organization> <dct:identifier rdf:datatype="http://www.w3.org/2001/XMLSchema#string">10.13039/501100000780</dct:identifier> <foaf:name>European Commission</foaf:name> </foaf:Organization> </frapo:isAwardedBy> </foaf:Project> </rdf:RDF>
