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.

UI MeSH Term Description Entries
D011108 Polymers Compounds formed by the joining of smaller, usually repeating, units linked by covalent bonds. These compounds often form large macromolecules (e.g., BIOPOLYMERS; PLASTICS). Polymer
D004573 Electrolytes Substances that dissociate into two or more ions, to some extent, in water. Solutions of electrolytes thus conduct an electric current and can be decomposed by it (ELECTROLYSIS). (Grant & Hackh's Chemical Dictionary, 5th ed) Electrolyte
