| Organoboron derivatives of 8-hydroxyquinoline have recently attracted much attention as potential alternatives to quinolato complexes of aluminum, Alq3, which serve as emission and electron-conduction layers in organic light emitting devices (OLEDs). Their polymeric analogs are of particular interest due to the potential opportunity of applying solution-processing methods in place of vacuum deposition for device fabrication. We describe here two different synthetic methods for the one-pot synthesis of luminescent organoboron quinolate polymers. We found that while the pendent boron substituents (variation of the aryl groups) only have a minor impact on the photophysical properties, tuning of the emission characteristics can very effectively be achieved through variation in the substituent pattern on the quinolato moiety. Thus, a facile modular synthetic route to a series of polymers with different luminescence properties is provided. |
