Substituted Polyfluorene-Based Hole Transport Layer with Tunable Solubility [PDF]

The Journal of Physical Chemistry C, 2010
We report on the synthesis and electrical characterization of polyfluorene-triarylamine-based hole transport layers (HTLs). The solubility of the HTL can be tuned by adjustment of the chemical structure without loss of the charge transport properties. Double-layer polymer light-emitting diodes are constructed with an HTL that is not soluble in toluene ...
