X-ray crystallography confirmed the saddle-shaped structures of intermediate 3 and NG 4. The favorability of rearrangement over helicene formation following radical cation or arenium cation mechanisms is supported by theoretical calculations. NG 4 demonstrates a reversible mechanochromic color change and solid-state emission, presumably benefiting from its loose crystal packing. After resolution by chiral high-performance liquid chromatography, the circular dichroism spectra of enantiomers 4-(P) and 4-(M) were measured and showed moderate Cotton effects at 350 nm  [Formula: see text].","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"American Chemical Society."}]},"item_10001_relation_13":{"attribute_name":"PubMedNo.","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:pmid/32809808","subitem_relation_type_select":"PMID"}}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1021/jacs.0c05504","subitem_relation_type_select":"DOI"}}]},"item_10001_relation_17":{"attribute_name":"Related site","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://pubs.acs.org/doi/10.1021/jacs.0c05504","subitem_relation_type_select":"URI"}}]},"item_10001_rights_15":{"attribute_name":"Rights","attribute_value_mlt":[{"subitem_rights":"© 2020 American Chemical Society."},{"subitem_rights":"ACS AuthorChoice with CC-BY."}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0002-7863","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"1520-5126","subitem_source_identifier_type":"ISSN"}]},"item_10001_version_type_20":{"attribute_name":"Author's flag","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2021-01-15"}],"displaytype":"detail","filename":"Qiu-2020-Negatively Curved Nanographene with H.pdf","filesize":[{"value":"2.1 MB"}],"format":"application/pdf","license_note":"Creative Commons Attribution 4.0 International(https://creativecommons.org/licenses/by/4.0/)","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Qiu-2020-Negatively Curved Nanographene with H","url":"https://oist.repo.nii.ac.jp/record/1881/files/Qiu-2020-Negatively Curved Nanographene with H.pdf"},"version_id":"eae98b50-d0ee-4c34-8e93-9da2371277eb"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Negatively Curved Nanographene with Heptagonal and [5]Helicene Units","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Negatively Curved Nanographene with Heptagonal and [5]Helicene Units","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"30","path":["177"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-01-15"},"publish_date":"2021-01-15","publish_status":"0","recid":"1881","relation_version_is_last":true,"title":["Negatively Curved Nanographene with Heptagonal and [5]Helicene Units"],"weko_creator_id":"30","weko_shared_id":30},"updated":"2023-06-26T11:41:10.368112+00:00"}
