Abstract

Abstract A series of 3, 7-bis (9, 9-di-n-hexylfluoren-2-yl)-N-arylphenothiazine-S, S-dioxide trimers and (9, 9-di-n-octylfluorene-2, 7-diyl-co-N-arylphenothiazine-S, S-dioxide) co- polymers, with varying ratios of phenothiazine-S, S-dioxide units, have been prepared in good yields by palladium-catalyzed cross-coupling reactions. The materials are deep blue emitters and show no solvatochromism or evidence for an intramolecular charge-transfer ...
