The quasi-reversible redox of dioxygen/O2•− is modified in the presence of caffeic acid, suggesting that O2•− is scavenged by caffeic acid through proton-coupled electron transfer. The reactivities of caffeic acid toward O2•− are mediated by the ortho-diphenol (catechol) moiety rather than by the acryloyl group, as experimentally confirmed in comparative analyses with other HCAs. The electrochemical and DFT results in DMF suggested that a concerted two-proton-coupled electron transfer mechanism proceeds via the catechol moiety. This mechanism embodies the superior kinetics of O2•− scavenging by caffeic acid.", "subitem_description_type": "Abstract"}]}, "item_10004_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "MDPI"}]}, "item_10004_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.3390/electrochem3030024", "subitem_relation_type_select": "DOI"}}]}, "item_10004_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "2673-3293", "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": "36619", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2023-03-20"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "electrochem-03-00024.pdf", "filesize": [{"value": "2.7 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_6", "mimetype": "application/pdf", "size": 2700000.0, "url": {"label": "electrochem-03-00024", "url": "https://gifu-pu.repo.nii.ac.jp/record/14854/files/electrochem-03-00024.pdf"}, "version_id": "659d2405-9c49-4e72-8824-531e9991288f"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "hydroxycinnamic acid", "subitem_subject_scheme": "Other"}, {"subitem_subject": "caffeic acid", "subitem_subject_scheme": "Other"}, {"subitem_subject": "superoxide radical anion", "subitem_subject_scheme": "Other"}, {"subitem_subject": "cyclic voltammetry", "subitem_subject_scheme": "Other"}, {"subitem_subject": "electron spin resonance spectrum", "subitem_subject_scheme": "Other"}, {"subitem_subject": "proton-coupled electron transfer", "subitem_subject_scheme": "Other"}, {"subitem_subject": "hydroxycinnamic acid", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "caffeic acid", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "superoxide radical anion", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "cyclic voltammetry", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "electron spin resonance spectrum", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "proton-coupled electron transfer", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}]}, "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 Hydroxycinnamic Acid Derivatives Involving Caffeic Acid toward Electrogenerated Superoxide in N,N-Dimethylformamide", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Reactivities of Hydroxycinnamic Acid Derivatives Involving Caffeic Acid toward Electrogenerated Superoxide in N,N-Dimethylformamide"}, {"subitem_title": "Reactivities of Hydroxycinnamic Acid Derivatives Involving Caffeic Acid toward Electrogenerated Superoxide in N,N-Dimethylformamide", "subitem_title_language": "en"}]}, "item_type_id": "10004", "owner": "140", "path": ["345"], "permalink_uri": "https://gifu-pu.repo.nii.ac.jp/records/14854", "pubdate": {"attribute_name": "公開日", "attribute_value": "2023-03-20"}, "publish_date": "2023-03-20", "publish_status": "0", "recid": "14854", "relation": {}, "relation_version_is_last": true, "title": ["Reactivities of Hydroxycinnamic Acid Derivatives Involving Caffeic Acid toward Electrogenerated Superoxide in N,N-Dimethylformamide"], "weko_shared_id": -1}
