title: All-conjugated triblock polyelectrolytes.
abstract: All-conjugated triblock polyfluorenes with well-defined molecular weights and low polydispersities are synthesized via chain-growth Suzuki-Miyaura polymerization. Ionization of pendant alkylbromide chains by pyridine affords amphiphilic triblock polyelectrolytes with neutral/charged/neutral or charged/neutral/charged segments. The immiscible blocks lead to aggregation in polar and nonpolar solvents, and to complex surface morphologies depending on the polarity of the substrate. These triblock polyelectrolytes can also be used as interfacial layers in polymer light-emitting diodes to facilitate electron injection from aluminum.
