摘要：

New fluorescent polymers for electroluminescent devices were synthesized and characterized. In order to obtain polymers for blue light emitting diodes (LEDs), two different structural concepts based on isolation of the active chromophore units within the polymer main chain were investigated. In the first approach non-coplanar units were used to reduce the conjugation length in poly(arylenevinylene)s. In a second approach copolymers having isolated chromophore units in the polymer main chain were investigated. For this purpose, copolyesters containing isolated 1,2-dinaphthylethene chromophore units were synthesized and characterized. The influence of the chemical structure on the photo- and electroluminescence is discussed. On the example of copolyester 2b, which shows bluegreen electroluminescence (lambda(max) = 497 nm) in a LED configuration, it was demonstrated that these polyesters can be used as light emitting layer in electrooptical devices.
