Abstract

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).
