We report a new class of luminescent polymers for easy color-tuning in polymer light-emitting diodes (PLEDs). By introducing various luminescent chromophores as pendants onto the polyureth-ane backbones, we obtained a series of polymers with emissions covering the visible range.
An analysis by using the Fowler-Nordheim tunneling model suggested that large barrier heights between the electrodes and the polymers mainly limited the device performance. With a proper choice ofelectrodes, therefore, we expect to develop full-color PLEDs by using this class of materials.
