The analytical use of polydentate ligands having plural \"aromatic-ring pendant arms,\" such as 2-pyridylmethyl, 1-pyrazolylmethyl and 2-hydroxyphenylmethyl groups, for not only the separation of cations, but also that of anions, was investigated fundamentally. These ligands generally have a specific nature at many points, such as hydrophobicity, electric effects, structural rigidity and sterical selectivity, originating from the aromatic-ring pendant arms; also, upon the mutual separation of many kinds of metal cations by solvent extraction they can act as extraction reagents having specific reaction selectivity. As one example, the extraction selectivity of divalent transition metal cations using N,N'-bis(2-hydroxyphenylmethyl)-N,N'-bis(2-pyridylmethyl)-1,2-ethanediamine (H_2bbpen) did not agree with the Irving-Williams series of stability; it was suggested that ion-size recognition based on the cavity size of the ligand acted in this extraction system. Upon the extraction of trivalent lanthanoids, as another example, N,N'-bis(5-nitrosalicylidene)-1,2-ethanediamine (H_2Nsalen) showed high performance for their mutual separation, originating from the structural ligidity of the ligand. Furthermore, an immobilized charged complex between bis(2-pyridylmethyl)amino group (bpa-group) and a metal cation was useful as an anion-exchange group in ion chromatography, having specific anion selectivity originating from its additional ligand-exchange ability.","subitem_description_type":"Abstract"}]},"item_4_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学理工研究域","subitem_description_type":"Other"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"The Japan Society for Analytical Chemistry = 日本分析化学会"}]},"item_4_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.jsac.or.jp/index.html","subitem_relation_type_select":"URI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://ci.nii.ac.jp/naid/110002905625/en/","subitem_relation_type_select":"URI"}}]},"item_4_rights_23":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright (c) 1999 日本分析化学会"}]},"item_4_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AN00222633","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0525-1931","subitem_source_identifier_type":"ISSN"}]},"item_4_version_type_25":{"attribute_name":"著者版フラグ","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":"平山, 直樹"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-10-03"}],"displaytype":"detail","filename":"SC-PR-HIRAYAMA-N-33.pdf","filesize":[{"value":"963.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SC-PR-HIRAYAMA-N-33.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/11076/files/SC-PR-HIRAYAMA-N-33.pdf"},"version_id":"4f3a9ad4-e044-4c72-9915-fcc110bb341d"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"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":"芳香環ペンダントアーム型多座配位子を用いるイオン分離へのアプローチ","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"芳香環ペンダントアーム型多座配位子を用いるイオン分離へのアプローチ"},{"subitem_title":"Approach to ion separation using polydentate ligands having aromatic-ring pendant arms","subitem_title_language":"en"}]},"item_type_id":"4","owner":"3","path":["937"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-03"},"publish_date":"2017-10-03","publish_status":"0","recid":"11076","relation_version_is_last":true,"title":["芳香環ペンダントアーム型多座配位子を用いるイオン分離へのアプローチ"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-07-28T01:33:21.285127+00:00"}
