Biscat 1 and Biscat 2 were characterized by X-ray crystal analysis and cyclic voltammetry (CV). The results from Xray crystal analysis shows that Biscat 1 and 2 possess a rod like structure with molecular lengths 14.7Å for Biscat 1 and 19.3Å for Biscat 2. In Biscat 1, the two catechol rings are not in the same plane and the dihedral angle of terminal catechol rings is about 25°. CVs for Biscat 1 and 2 were measured under alkaline conditions. An oxidation wave was observed corresponding to Sq-Sq (Sq: semiquinone)→Bq-Bq (Bq: benzoquinone) at around -300 mV. However, the redox waves disappeared when the CV scan was repeated. In contrast, Biscat 3 showed stable redox waves in the range from -1 V to ＋1.5 V even in alkaline conditions. These results suggest that Biscat 1 and 2 were converted into polymer or oligomer compounds (insoluble materials) through the Bq-Bq structures during repeat of the CV scans.","subitem_description_type":"Abstract"}]},"item_2_description_41":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_2_publisher_14":{"attribute_name":"出版者 名前","attribute_value_mlt":[{"subitem_publisher":"近畿大学理工学総合研究所"}]},"item_2_source_id_22":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09162054","subitem_source_identifier_type":"ISSN"}]},"item_2_text_7":{"attribute_name":"著者(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"&EMPTY&"},{"subitem_text_language":"en","subitem_text_value":"&EMPTY&"},{"subitem_text_language":"en","subitem_text_value":"&EMPTY&"},{"subitem_text_language":"en","subitem_text_value":"&EMPTY&"},{"subitem_text_language":"en","subitem_text_value":"前川, 雅彦"}]},"item_2_text_8":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"Department of Chemistry, Kinki University:Research Institute for Science and Technology, Kinki University"},{"subitem_text_value":"Department of Chemistry, Kinki University"},{"subitem_text_value":"Department of Chemistry, Kinki University"},{"subitem_text_value":"Department of Chemistry, Kinki University"},{"subitem_text_value":"Research Institute for Science and Technology, Kinki University"}]},"item_2_version_type_12":{"attribute_name":"版","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Suenaga,  Yusaku"},{"creatorName":"スエナガ, ユウサク","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hirano,  Yasuhiro"},{"creatorName":"ヒラノ, ヤスヒロ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Umehata,  Yukiko"},{"creatorName":"ウメハタ, ユキコ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kamei,  Kuniaki"},{"creatorName":"カメイ, クニアキ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Maekawa,  Masahiko"},{"creatorName":"マエカワ, マサヒコ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-02-19"}],"displaytype":"detail","filename":"AN10074306-20110228-0023.pdf","filesize":[{"value":"4.7 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AN10074306-20110228-0023.pdf","url":"https://kindai.repo.nii.ac.jp/record/11144/files/AN10074306-20110228-0023.pdf"},"version_id":"d390bfe9-a381-4f66-8289-d102a39612b9"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"bis(catechol)","subitem_subject_scheme":"Other"},{"subitem_subject":"acetylene group","subitem_subject_scheme":"Other"},{"subitem_subject":"rod like structure","subitem_subject_scheme":"Other"},{"subitem_subject":"electrochemical behavior","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Syntheses, crystal structures and electrochemical properties of bis(catechol)s with acetylene group","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Syntheses, crystal structures and electrochemical properties of bis(catechol)s with acetylene group","subitem_title_language":"en"}]},"item_type_id":"2","owner":"3","path":["2101","3567"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-05-14"},"publish_date":"2011-05-14","publish_status":"0","recid":"11144","relation_version_is_last":true,"title":["Syntheses, crystal structures and electrochemical properties of bis(catechol)s with acetylene group"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-06-20T20:42:36.640444+00:00"}
