Energy transfer processes allow for a significant increase in efficiency of organic light-emitting devices by utilizing all excited states generated from electron-hole recombination, in particular non-emissive triplet excitons. Therefore, the preparation of composites, which exhibit triplet energy transfer through molecular photonic wire behavior, could be of practical importance for the fabrication of efficient OLEDs. In this poster, we demonstrate the first example of molecular wire behavior in donor-bridge-acceptor electroluminescent triads, which comprise aluminum tris(8-quinolinolate) as an energy donor (³Alq₃ = 2.17 eV), fluorene oligomers as connecting bridge (³OF_1-4 = 2.86-2.18 eV), and platinum tetraphenylporphyrin as an energy acceptor (³PtTPP =1.91 eV). Efficient singlet and triplet energy transfer is observed in these systems, which show pure red phosphorescence emission. Furthermore, improved OLED output was obtained for triads having longer oligofluorene bridges showing better alignment of triplet energy levels despite the longer donor-acceptor distance.
