Облучение пленок комплексов поляризованным светом (457 нм) приводит к ориентации обоих типов мезогенных групп в направлении перпендикулярном плоскости поляризации падающего света. Обнаружено, что величина наведенного дихроизма D азо-групп в три раза больше для комплекса блочного строения, чем для комплекса статистического строения. Показано, что микрофазово разделенная структура полимерного комплекса играет важную роль в механизме и протекании фотоориентационных процессов, а также в проявлении кооперативного эффекта между фотохромными и нефотохромными мезогенными группами.","PeriodicalId":18138,"journal":{"name":"Liquid Crystals and their Application","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2023-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46631574","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Благодаря этому они находят широкое применение в различных приборах молекулярной электроники. Однако в этой области помимо синтеза большого количества новых соединений, в последние годы значительное внимание ученых привлекает возможность внедрения в ЖК-среды различных допантов, что потенциально может стать экономически эффективным способом улучшения параметров ЖКиндикаторов. В качестве компонентов ЖК-смесей могут выступать металлоорганические комплексы, металлические наночастицы (НЧ), полупроводниковые НЧ, сегнетоэлектрические НЧ, диэлектрические НЧ. В данной работе исследовано влияние введения мезогенного комплекса европия(III) и парамагнитных квантовых точек в коммерчески доступные ЖК-среды. Были получены ЖК-материалы с разнесенными максимумами возбуждения, что позволило селективно сенсибилизировать люминесценцию ЖКсмеси, квантовых точек и комплекса Eu(III). Таким образом, варьируя длину волны возбуждения люминесценции в диапазоне от 340 нм до 390 нм, можно получать различный цвет люминесценции, в том числе и белый. Такие материалы могут найти практическое применение в перестраиваемых лазерах, органических светодиодах и других устройствах обработки и отображения информации.","PeriodicalId":18138,"journal":{"name":"Liquid Crystals and their Application","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2023-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42311188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
