Abstract
Electroluminescence is an important and much studied property of semiconducting films of conjugated organic polymers [1,2,3,4], and is the basis of their commercial application in organic light emitting diodes (oLEDs) [5,6,7,8]. These have the potential to be more efficient, more easily scalable, and more flexible than their inorganic counterparts [7, 9, 10]. oLEDs are constructed in four layers: a thin film of the semiconducting polymer is sandwiched between an electron-injecting metal cathode and a transparent hole-injecting layer, which is then covered by a transparent anode. Calcium and aluminium are commonly used for the cathode and indium tin oxide for the anode, with poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT-PSS) a typical hole-injecting layer [11,12,13,14,15]. In this chapter, we are concerned with the properties of the semiconducting polymer layer which affect the efficiency of electroluminescence.
