倍以上の光耐久性を有する新たなペンタセン誘導体の開発に成功し、関西学院大学の橋本秀樹教授らのグループと共同で、この系の超高速励起状態ダイナミクスを明らかにしました。この系のペンタセン部位では、励起一重項状態から励起三重項状態への遷移が百フェムト秒(10^{-13} 秒)という時間領域で超高速に起こっていることを実証できました。レアメタルなどの重原子を含まない純粋な有機物では、このような系間交差は通常ナノ秒(10^{-9}

both π-radical- and TIPS-substituents (1m and 1p) were synthesized and their photochemical properties and excited-state dynamics were evaluated. The pentacene-radical-linked systems 1m (1p) showed a remarkable improvement in photochemical stability, which was 187 (139) times higher than that of 6,13-bis(triisopropylsilylethynyl)pentacene. Transient absorption spectroscopy showed that this remarkable photostabilization is due to the ultrafast intersystem crossing induced by effective π-conjugation between the radical substituent and pentacene moiety. The relationship between π-topology and the photochemical stability is also discussed based on the excited-state dynamics.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"This work was financially supported by the Grant-in-Aid for Scientific Research(B)(No. 16H04136, No. 20H02715) and Grant-in-Aid for Challenging Exploratory Research (No. 18K19062) from the Japan Society for the Promotion of Science(JSPS).","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Royal Society of Chemistry ","subitem_publisher_language":"en"}]},"item_1617186783814":{"attribute_name":"識別子","attribute_value_mlt":[{"subitem_identifier_type":"DOI","subitem_identifier_uri":"https://doi.org/10.1039/D2CP00683A"}]},"item_1617186920753":{"attribute_name":"収録物識別子","attribute_value_mlt":[{"subitem_source_identifier":"1463-9084","subitem_source_identifier_type":"ISSN"}]},"item_1617187056579":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"2022-06-14","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"22","bibliographicPageEnd":"13518","bibliographicPageStart":"13514","bibliographicVolumeNumber":"24","bibliographic_titles":[{"bibliographic_title":"Physical Chemistry Chemical Physics","bibliographic_titleLang":"en"}]}]},"item_1617258105262":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_1617353299429":{"attribute_name":"関連情報","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"AA11723355","subitem_relation_type_select":"NCID"}}]},"item_1722232185104":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-06-15"}],"displaytype":"detail","filename":"14639084-24-22-13514.pdf","filesize":[{"value":"3.3 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"本文","objectType":"fulltext","url":"https://ocu-omu.repo.nii.ac.jp/record/2020390/files/14639084-24-22-13514.pdf"},"version_id":"d6f09ba9-e18e-4951-9939-4a79d681ee69"}]},"item_1722577087681":{"attribute_name":"記事種別等","attribute_value_mlt":[{"subitem_description":"Paper","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_1725590125188":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_title":"π-Topology and ultrafast excited-state dynamics of remarkably photochemically stabilized pentacene derivatives with radical substituents","item_type_id":"40002","owner":"7","path":["1721355153493"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2022-06-15"},"publish_date":"2022-06-15","publish_status":"0","recid":"2020390","relation_version_is_last":true,"title":["π-Topology and ultrafast excited-state dynamics of remarkably photochemically stabilized pentacene derivatives with radical substituents"],"weko_creator_id":"7","weko_shared_id":-1},"updated":"2024-10-31T02:31:31.734511+00:00"}
