Blue polymer light-emitting diodes from poly (9,9-dihexylfluorene-alt-co-2, 5-didecyloxy-para-phenylene)
Appl. Phys. Lett., Vol. 75, No.21, 22 November 1999, 3270-3272,-0001,():
Deep blue photoluminescence and electroluminescence are demonstrated from a soluble conjugated polymer, poly (9,9-dihexylfluorene-alt-co-2,5-didecyloxy-para-phenylene). The PL quantum efficiency is approximately 40%. Cyclic voltammetry measurements indicate that the highest occupied molecular orbital and lowest unoccupied molecular orbital energies are 5.66 and 2.62 eV below vacuum, respectively. Single-layer and multilayer light-emitting diodes emit deep blue light (peak at; 420nm).
