AbstractTwo new electroluminescent copolymers containing biquinolines and 2,2-diphenylhexafluoropropane (F-PQ) or pyridine (Py-PQE) moieties were prepared. They possess excellent thermal stability (decomposition temperature greater than 500 degreesC), good electrochemical reversibility in reduction reactions, and high electron affinity. The energy levels for HOMO and LUMO determined by cyclic voltammetry were -5.80 and -2.89 eV for F-PQ, and -5.88 and -2.66 eV for Py-PQE, respectively. Electrical characterization of a double layer light emitting diode (LED) based on the structure of ITO/copper phthalocyanine (CuPc)/F-PQ/Al showed good performance (a rectification ratio greater than 10(5) and a low turn-on voltage of 6.2 V). A single layer LED fabricated with Py-PQE as an emitting layer and air-stable aluminium as a cathode exhibited a balanced injection/transport of hole and electron. A luminance of 94.0 cd m(-2) was observed from a double layer LED of ITO/CuPc/Py-PQE/Al at a current density of 141.4 mA cm(-2).
