Supramolecular photophysics of self-assembled block copolymers containing luminescent conjugated polymers

Article Abstract:

The luminescent micellar aggregates and spherical vesicles self-assembled from polyquinoline-polystyrene diblock and polyquinoline-polystyrene-polyquinoline triblock copolymers are investigated by photoluminescence excitation and emission spectroscopies and fluorescence microscopy. In both the diblock miscelles and triblock vesicles, new absorption and emission features characteristic of the supramolecular morphology in solution and the solid state were observed.

Field-effect mobility of charge carriers in blends of regioregular poly(3-alkylthiophene)s

Article Abstract:

The thin film transistors based on regioregular poly(3-hexylthiophene) and poly(3-decylthiophene) and their binary blends were investigated and the blend composition dependence of the charge carrier mobility was determined. These results demonstrate that blends of conjugated polymers are alloy semiconductors in which high and tunable charge carrier mobility can be realized.

Multiple Electrochemical Doping-Induced Insulator-to-Conductor Transitions observed in the Conjugated Ladder Polymer

Article Abstract:

Doping-induced reactions in conjugated polymers are studied by spectroelectrochemical techniques. The results on reduction reactions (n-doping) of the conjugated ladder polymer polybenzimidazobenzophenanthroline (BBL) are reported.
