Abstract:
Summary: A p – n di‐channel copolymer based on polyfluorene (PF) has been designed and prepared. Branches containing oxadiazole units are attached to the PF backbone through the spiro‐structure and act as channels to improve the electron affinity; these branches form a steric ‘di‐channel’ framework with the polymer backbone. The polymer possesses excellent thermal stability. The lowest unoccupied molecular orbital energy level of the polymer is significantly altered in comparison with poly(9,9‐dioctylfluorene‐2,7‐diyl). Schematic of the di‐channel polyfluorene synthesized here and the mechanism of energy transfer through the structure. magnified image Schematic of the di‐channel polyfluorene synthesized here and the mechanism of energy transfer through the structure.
