Crosslinkable condensed aromatic amines as materials for insoluble hole transporting layers

Abstract

Cross-linkable aromatic amines have been synthesized by the multi-step synthetic rout. Full characterization of their structure by HNMR and mass spectroscopy as well as IR spectrometry is presented. The synthesized materials were examined by various techniques including differential scanning calorimetry, thermogravimetry, UV and electron photoemission spectrometry. The electron photoemission spectra of the layers showed their ionisation potentials of 5.1-5.25 eV. One of the derivatives was used for preparation of insoluble hole transporting layers by photoinduced polymerization. The layers obtained were tested in light emitting diodes
