## Abstract Poly(fluorene)โtype materials are widely used in polymerโbased emitting devices. During operation there appears, however, an additional emission peak at around 2.3 eV, leading to both a color instability and reduced efficiency. The incorporation of the carbazole units has been proven to
## Abstract **Summary:** A well defined blue electroluminescent fluoreneโcarbazolโfluorene trimer 3,6โbisโ(9,9โdihexylโ9__H__โfluorenโ3โyl)โ9โalkylโ9__H__โcarbazole was synthesized using a Suzuki type cross coupling reaction as the key step. A way to attach this chromophore to a norbornene was deve
