Introduction Conducting conjugated polymers which provide flexibility as polymers as well as conductivity as metals have nowadays become an essential solution-processable material for fabricating polymer light-emitting diodes PLEDs and plastic solar cells. In addition to the possibility of producing large-area thin films at room temperature an appealing feature of exploiting long-chain organic semiconductors lies in the capability to fine-tune the optoelectronic behavior of solution-cast films by exploiting a broad variety of solvents or hybrid solvents in preparing the precursor solutions later fabricated into dry thin films via spin coating or ink-jet printing. To improve the solubility in usual organic solvents the polymers are often modified by grafting flexible alkyl or alkoxy side chains to the phenyl backbone rendering the polymer chemical amphiphilicity. The semiflexible backbone and chemical amphiphilicity in turn give rise to a vast swath of single-chain and aggregation morphologies as different types of solvents are used to cast the polymer thin films through mechanisms generally referred to as the memory effect Nguyen et al. 1999 as .
