π-Conjugated oligomers and polymers

π-Conjugated polymers have been extensively investigated as active components in organic electronic devices and molecular electronics. They have been used in the fabrication of organic light emitting diodes (OLEDs) or lasers,  organic field-effect transistors (OFETs),  integrated circuits and organic solar cells (OSCs).  Additionally, monodisperse π-conjugated oligomers and dendrimers   have received in recent years a great deal of attention given that they are excellent model compounds for the corresponding polydisperse polymers which include chain length distributions, defects and interruptions of the conjugated chains. Conjugated oligomers have been of major importance for establishing structure–property relationships and extrapolations to the polymer have been established by monitoring how different properties depend on the chain length which is the so-called oligomeric approach.
