Cyclicvoltammetry and in situ electrolytic electron spin resonance measurements revealed that the quinone–hydroquinone π-conjugation plays an important role in a successful O2•− scavenging by 12H2NQ and 14H2NQ through proton-coupled electron transfer (PCET) reaction. The reactivities of 12H2NQ and 14H2NQ toward O2•− were mediated by the ortho- (catechol) or para-diphenol (hydroquinone) moieties, as experimentally confirmed in comparative analyses with catechol, hydroquinone, and 13H2NQ, aided by density functional theory (DFT) calculations. The electrochemical and DFT results suggested that a concerted PCET mechanism involving two-proton transfers and one-electron transfer proceeds, demonstrating a successful O2•− scavenging by 12H2NQ and 14H2NQ. Furthermore, a subsequent electron transfer between molecular dioxygen and product-naphthoquinone-radicals was observed, where O2•− was regenerated. The DFT analysis suggested that the spin distribution on the planar naphthalene ring embodies the superior kinetics of the PCET and the subsequent generation of O2•− from dioxygen demonstrated in the electrochemical results.", "subitem_description_type": "Abstract"}]}, "item_10004_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "Elsevier"}]}, "item_10004_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.1016/j.electacta.2022.141467", "subitem_relation_type_select": "DOI"}}]}, "item_10004_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "00134686", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "nakayama, tatsushi"}], "nameIdentifiers": [{"nameIdentifier": "32440", "nameIdentifierScheme": "WEKO"}, {"nameIdentifier": "N000638361", "nameIdentifierScheme": "CiNii ID", "nameIdentifierURI": "http://ci.nii.ac.jp/nrid/N000638361"}]}, {"creatorNames": [{"creatorName": "Uno, Bunji"}], "nameIdentifiers": [{"nameIdentifier": "36618", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_login", "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "1-s2.0-S0013468622016243-main.pdf", "filesize": [{"value": "2.8 MB"}], "format": "application/pdf", "future_date_message": "Restricted Access", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 2800000.0, "url": {"label": "1-s2.0-S0013468622016243-main", "url": "https://gifu-pu.repo.nii.ac.jp/record/14853/files/1-s2.0-S0013468622016243-main.pdf"}, "version_id": "1adcdfd3-fd15-48d2-8181-3fa0a63c1fc9"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "資源タイプ", "attribute_value_mlt": [{"resourcetype": "article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Reactivities of 1,2-, 1,3-, and 1,4-dihydroxynaphthalenes toward electrogenerated superoxide in N,N-dimethylformamide through proton-coupled electron transfer", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Reactivities of 1,2-, 1,3-, and 1,4-dihydroxynaphthalenes toward electrogenerated superoxide in N,N-dimethylformamide through proton-coupled electron transfer"}, {"subitem_title": "Reactivities of 1,2-, 1,3-, and 1,4-dihydroxynaphthalenes toward electrogenerated superoxide in N,N-dimethylformamide through proton-coupled electron transfer", "subitem_title_language": "en"}]}, "item_type_id": "10004", "owner": "140", "path": ["345"], "permalink_uri": "https://gifu-pu.repo.nii.ac.jp/records/14853", "pubdate": {"attribute_name": "公開日", "attribute_value": "2023-03-20"}, "publish_date": "2023-03-20", "publish_status": "0", "recid": "14853", "relation": {}, "relation_version_is_last": true, "title": ["Reactivities of 1,2-, 1,3-, and 1,4-dihydroxynaphthalenes toward electrogenerated superoxide in N,N-dimethylformamide through proton-coupled electron transfer"], "weko_shared_id": -1}
