  Crosslinkable Fluorene-Based Derivatives as Materials for Light Emitting Diodes

  摘要：

  A series of cross-linkable fluorene-based derivatives have been synthesized by the multistep synthetic rout. Characterization of their structure by H-1 NMR and mass spectrometry is presented. The synthesized materials were examined by various techniques including differential scanning calorimetry, thermogravimetry, UV, fluorescence and electron photoemission spectrometries. It is established that the new derivatives have large triplet energies and could be used as host materials in phosphorescent light emitting diodes. The device fabricated with the use of one of the new hosts reached a brightness of 1700 cd/m(2) and a current efficiency of 3.4 cd/A.

  Fluorenyl-substituted aromatic amines containing reactive oxetanyl groups have been synthesized. Full characterization of their structure by NMR-, IR- and mass spectrometry is presented. The synthesized materials were examined by various techniques including differential scanning calorimetry, thermo-gravimetry, electron photoemission spectrometry and xerographic time of flight technique. The electron photoemission spectra of the layers of the derivatives showed ionization potentials of 5.4-5.65 eV. These derivatives have been tested as hole transporting materials in bilayer OLEDs with Alq(3) as the emitter. The device with derivative containing benzidine core exhibited the best overall performance with turn-on voltage of similar to 2.5 V. a maximum luminance efficiency of 4 cd/A and maximum brightness of about 6000 cd/m(2). The derivative was also used for the preparation of cross-linked hole transporting layers by photoinduced polymerization. The layers obtained were also tested in light emitting diodes. The devices demonstrated maximum photometric efficiency of 1.65 cd/A and maximum brightness of about 3000 cd/m(2). (c) 2011 Elsevier Ltd. All rights reserved.
