Elctroluminescence: A bright future for conjugated polymers?

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.
