Liquid-crystalline TADF materials based on substituted carbazoles and terephthalonitrile

Liquid-crystalline TADF materials based on substituted carbazoles and terephthalonitrile

By functionalising 2,5-di( N,N ′-carbazolyl)terephthalonitrile or 2,3,5,6-tetra( N,N ′-carbazolyl)terephthalonitrile with alkoxy chains located on the carbazole moiety, a family of materials is realised, all of which show a TADF response and two of which are also liquid crystalline. Functionalising...

Zusammenfassung:By functionalising 2,5-di( N,N ′-carbazolyl)terephthalonitrile or 2,3,5,6-tetra( N,N ′-carbazolyl)terephthalonitrile with alkoxy chains located on the carbazole moiety, a family of materials is realised, all of which show a TADF response and two of which are also liquid crystalline. Functionalising 2,5-di( N,N' -carbazolyl)terephthalonitrile or 2,3,5,6-tetra( N,N' -carbazolyl)terephthalonitrile on the carbazole moiety with alkoxy chains, gives a family of materials that show TADF response; two of them are also liquid crystalline.
