No clear difference in the concentration of the effective intrinsic trap sites was observed between PVCz(r) and PVCz(c) films. The concentration of the sandwich-like excimer site(cE) in a PVCz(r) film was nearly equal to that in a PVCz(c) film, while the concentration of the second excimer site (cS) in a PVCz(r) film was higher than that in a PVCz(c) film by a factor of about 1.6. The value of cE was much larger than that of cS for both films. The second excimer site seems to be a shallow trap. The number of carbazolyl chromophores covered by a singlet exciton during the lifetime was in the following order: PCzEVE&gt;PVCz(r)≈PVCz(c)&gt;PACz≈BPVCz. This order was explained by the concentration of the intrinsic trap sites depending on the distance between neighboring Cz chromophores, the lifetime of the singlet exciton, and the concentration of extrinsic trap sites.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1580572702793894912","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000020482068"},{"@type":"NRID","@value":"9000020384741"}],"foaf:name":[{"@value":"Akira Itaya"}],"jpcoar:affiliationName":[{"@value":"Department of Chemical Engineering, Faculty of Engineering, Yamaguchi University"}]},{"@id":"https://cir.nii.ac.jp/crid/1580572702793895040","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000020482075"},{"@type":"NRID","@value":"9000020384751"}],"foaf:name":[{"@value":"Ken-ichi Okamoto"}],"jpcoar:affiliationName":[{"@value":"Department of Chemical Engineering, Faculty of Engineering, Yamaguchi University"}]},{"@id":"https://cir.nii.ac.jp/crid/1580572702793894913","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000020482080"},{"@type":"NRID","@value":"9000020384757"}],"foaf:name":[{"@value":"Shigekazu Kusabayashi"}],"jpcoar:affiliationName":[{"@value":"Department of Chemical Engineering, Faculty of Engineering, Yamaguchi University"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"00092673"},{"@type":"EISSN","@value":"13480634"}],"prism:publicationName":[{"@value":"Bulletin of the Chemical Society of Japan"}],"dc:publisher":[{"@value":"Oxford University Press (OUP)"}],"prism:publicationDate":"1977-01-01","prism:volume":"50","prism:number":"1","prism:startingPage":"22","prism:endingPage":"26"},"reviewed":"false","dcterms:accessRights":"http://purl.org/coar/access_right/c_abf2","dc:rights":["https://academic.oup.com/pages/standard-publication-reuse-rights"],"url":[{"@id":"https://academic.oup.com/bcsj/article-pdf/50/1/22/56094918/bcsj.50.22.pdf"},{"@id":"https://academic.oup.com/bcsj/article-pdf/49/8/2037/56086466/bcsj.49.2037.pdf"}],"createdAt":"2006-07-20","modifiedAt":"2024-01-17","foaf:topic":[{"@id":"https://cir.nii.ac.jp/all?q=General%20Chemistry","dc:title":"General Chemistry"}],"relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1050282677631354752","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Self-assembled polycarbazole microspheres as single-component white-colour resonant photoemitters"}]},{"@id":"https://cir.nii.ac.jp/crid/1360002219100203904","@type":"Article","relationType":["references"],"jpcoar:relatedTitle":[{"@value":"The Migration of Electronic Excitation Energy in Copolymers of <i>N</i>-Vinylcarbazole with a Small Content of Styrene or Vinyl Acetate"}]},{"@id":"https://cir.nii.ac.jp/crid/1360002219100514944","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Emission Spectra of the Vinyl Polymers with Pendant Carbazolyl Groups"}]},{"@id":"https://cir.nii.ac.jp/crid/1360002219101059456","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Emission Spectra of the Vinyl Polymers with Pendant Benzocarbazolyl Groups"}]},{"@id":"https://cir.nii.ac.jp/crid/1360002219101148544","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Photo-oxidation Effect of Poly(<i>N</i>-vinylcarbazole) Film on Photoconductivity and Electronic Spectra"}]},{"@id":"https://cir.nii.ac.jp/crid/1360011145513568384","@type":"Article","relationType":["references"],"jpcoar:relatedTitle":[{"@value":"Intramolecular Triplet Energy Transfer in Poly(1-vinylnaphthalene)"}]},{"@id":"https://cir.nii.ac.jp/crid/1360283694076958976","@type":"Article","relationType":["references"],"jpcoar:relatedTitle":[{"@value":"Charge-transfer Complexes of Vinyl Polymers with Large Pendant π-electron Systems.
