Molecular-Wire Behavior of OLED Materials:Exciton Dynamics in Multichromophoric Alq_3-Oligofluorene-Pt(II)porphyrin Triads

摘要

A successful development of flat displays utilizing organic light-emitting diodes technology(OLED)depends on the availability of organic semiconductors capable of emitting light with high electron-to-photon quantum efficiency.Because of the spin statistics of hole-electron recombination that produces three triplets per one singlet,triplet emitters are preferred over singlet emitters to increase the device efficiency.
