PPV-derivatives containing phenothiazine and alkyloxy-substituted oxadiazole/Phenyl units for OLED
2005
The heterocycle of phenothiazine unit was investigated as the backbone of organic light-emitting polymeric materials because of its strong luminescence, potential ability of anti-oxidation and p-type semiconductor properties. The dialdehyde and dibromo-substituted phenothiazines were synthesized successfully by Vilsmeier method and bromination respectively. The homo and co-polymers from phenothiazine and substituted oxadiazole were synthesized successfully. Their photo- and electroluminescent properties were investigated.
