Photophysics luminescent conjugated polymers

The role of disorder in the photophysics of conjugated polymers has been extensively described by the work carried out in Marburg by H. Bassler and coworkers. Based on ultrafast photoluminescence (PL) (15], field-induced luminescence quenching [16J and site-selective PL excitation [17], a model for excited state thermalizalion was proposed, which considers interchain exciton migration within the inhomogenously broadened density of states. We will base part of the interpretation of our results in m-LPPP on this model, which will be discussed in some detail in Sections 8.4 and 8.6.

PFs are a fascinating family of conjugated polymers. Their unique luminescence properties make them ideal model systems to study new physical phenomena in conjugated polymers at the single molecule level—effects which are usually masked in the ensemble photophysical studies, but are nevertheless absolutely crucial to determining the bulk material properties.
