摘要
The novel family of hole transporting polymers containing hydrazone moieties is reported. The polymers were prepared in polyaddition reaction of hydrazone-containing diepoxydes with 2,5-dimercapto-1,3,4-thiadiazole in the presence of catalyst thriethylamine (TEA). Obtained polymers were found to constitute novel polymeric hole transporting materials (TM) characterized by differential scanning calorimmetry (DSC) and time of flight method. The highest hole-drift mobility in the newly synthesized polymers exceed 10(-5) cm(2) V-1 s(-1) at an electric field of 10(6) V cm(-1) was observed in the TM with triphenylamine moieties. The electron photoemission spectra of the obtained polymers have been recorded and the ionization potentials of 5.24-5.33 eV have been determined. (c) 2005 Elsevier B.V. All rights reserved.
