Conjugated polymer electroluminescence has recently been attracting a great deal of attention. The color range achievable now spans red, gree, and blue, and it has also been shown that polymer-based light-emitting diodes can be formed as flexible structures. Progress made in the synthesis of the polymers, the patterning of thin films of the polymers for application in large-area displays, the improvement of device efficiencies, and teh identification of the charge carriers involved is discussed.
