AbstractEfficient white light emission has been recently reported in an electroluminescent device where the active material is a complex made of N,N'-bis(alpha-naphthyl)-N,N'-diphenyl-1,1'-biphenyl-4,4-diamine (NPB) and a boron-fluorine derivative of 1,6-bis(2-hydroxy-5-methylphenyl)pyridine ((mdppy)BF). Here, we investigate theoretically the intermolecular charge transfer in the materials. The interfacial layer is modeled on the basis of a simple dimer structure, for which the lowest excited states are described in the framework of a correlated quantum-chemical semiempirical technique. From the analysis of the calculated excited-state wavefunctions, we find that the lowest excited state possesses significant contributions from charge-transfer excitations from the donor (NPB) to the acceptor ((mdppy)BF). The influence of intermolecular distance and medium polarization are also explored. (C) 2003 Elsevier B.V. All rights reserved.
