Compound 2 showed monomer and excimer emissions in both an organic and aqueous, which was contained a 10 vol.% DMF, solution, whereas compound 1 indicated these two emissions in only aqueous solution. The fluorescence spectral patterns of compounds 1 and 2 were changed depending on DMF concentrations in an aqueous solution. The extent of the excimer emission of 2 was the highest in a 50 vol.% DMF, whereas drastic decrease of this excimer emission was observed in over 60 vol.% DMF. On the other hand, compound 1 showed the highest excimer emission intensity between 10-30 vol.% DMF and middle emission was recognized in 30 vol% DMF. Finally, in over 50 vol.% DMF, no excimer emission of 1 was observed. The movements of the appended units of these compounds in various DMF concentrations were studied by the fluorescence and UV spectra and MM2-minimized structures. A ratio of excimer and monomer emission intensities of 1 and 2 were varied in 10-40 vol.% and 10-50 vol.% DMF contents in water, respectively. The UV spectra patterns of 1 or 2 were different between in 10-40 vol.%, 50 vol.% and over 60 vol.% or 10-50 vol.%, 60 vol.% and over 70 vol.% DMF aqueous solutions, respectively. The variations of fluorescence and UV spectra suggested that compounds 1 and 2 formed association dimer in 10-40 vol.% and 10-50 vol.% DMF aqueous solutions, respectively, and the canceling of these dimer formations was observed with increasing DMF content or metal concentration. Furthermore, fluorescent spectral changes and MM2-minimized structures suggested that the association dimer of 2, which formed one pair pyrene excimer in 10 vol.% DMF aqueous solution, was transformed into different configuration of association dimer making plural pyrene excimer pairs in 20-50 vol.% DMF aqueous solutions. In order to evaluate the metal sensing abilities of 1 and 2 in a 10 vol.% DMF aqueous solution, the ratio of decrement of an intensity of excimer emission with an addition of metal cation was used as a detecting parameter. Compounds 1 and 2 exhibited the highest sensing abilities for Na2+ and Co2+, respectively.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"The Society of Materilas Engineering for resources of Japan","subitem_publisher_language":"en"}]},"item_10001_relation_25":{"attribute_name":"関連情報","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.5188/ijsmer.10.106","subitem_relation_type_select":"DOI"}}]},"item_10001_version_type_20":{"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_1724099666130":{"attribute_name":"収録物識別子","attribute_value_mlt":[{"subitem_source_identifier":"13479725","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"AA1095475X","subitem_source_identifier_type":"NCID"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"作成者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Kondo, Yoshihiko","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Yamazaki, Yoshiaki","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Nashirozawa, Norio","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Narita, Miyuki","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Hamada, Fumio","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-02-16"}],"displaytype":"detail","filename":"ijsmer10-1q.pdf","filesize":[{"value":"868.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ijsmer10-1q.pdf","url":"https://air.repo.nii.ac.jp/record/958/files/ijsmer10-1q.pdf"},"version_id":"0f257187-0bbe-4489-8236-d33307fd1860"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Cavitand","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Pyrene","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Metal sensing","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Supramolecular formation","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Supramolecular Formation of Mono- and Bis-Modified Pyrene Cavitands and Their Fluorogenic Metal Sensory System in an Aqueous Solution","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Supramolecular Formation of Mono- and Bis-Modified Pyrene Cavitands and Their Fluorogenic Metal Sensory System in an Aqueous Solution","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"15","path":["682"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-03-28"},"publish_date":"2008-03-28","publish_status":"0","recid":"958","relation_version_is_last":true,"title":["Supramolecular Formation of Mono- and Bis-Modified Pyrene Cavitands and Their Fluorogenic Metal Sensory System in an Aqueous Solution"],"weko_creator_id":"15","weko_shared_id":-1},"updated":"2024-08-25T10:42:04.583643+00:00"}
