ACS Materials Letters, 6(8), 3909-3914.2639-4979https://scholarworks.montana.edu/handle/1/18816Despite most porous framework solids exhibiting insulating character, some are known to conduct electrical charge. The peak performing conductive metal–organic frameworks are composed of redox-active hexasubstituted triphenylene linkers, but the impact of redox activity on material conductivity remains enigmatic because of limited availability of direct structure–function relationships. Here, we report a hexagonal yttrium-based conductive porous scaffold, comprising hexahydroxytriphenylene connected by Y-chains (YHOTP). In comparison to its known porous cubic counterpart (Y6HOTP2), this material features a 1000-fold increase in peak conductivity in polycrystalline samples (∼10–1 S cm–1). Furthermore, through a comparison of their electronic structures, we rationalize the origin of this difference and highlight the role of charge carrier concentration in dictating bulk electrical conductivity. Together, this work provides a design principle for the development of next-generation conductive porous frameworks.en-USCopyright American Chemical Society 2024http://web.archive.org/web/20190502075603/http://pubs.acs.org/paragonplus/copyright/jpa_form_a.pdfcarrier dynamicselectrical conductivityligandsmaterialsmetal organic frameworksArticle10.1021/acsmaterialslett.4c01102
