Title
Polymers with covalently attached dyes - materials for OLEDs and photovoltaics?
Abstract
An unusual way is presented to obtain a new class of deep red emitting polyurethanes with covalently attached fluorescent dyes. The DCM-dye seems to be a favourable candidate but we had to introduce two reactive hydroxy linker groups into the molecule to enable polymerization. By copolymerization with non-dye molecules the dye content in the main chain can be varied. Red emitting device structures were realized and some of the device properties will be given.
