Novel hydrazone based polymers as hole transporting materials
Santrauka
The novel family of hole transporting polymers containing hydrazone moieties is reported. The polymers were prepared in polyaddition reaction of hydrazone-containing diepoxydes with 4,4'-thiobisbenzenethiol in the presence of catalyst triethylamine (TEA). Obtained polymers were found to constitute novel polymeric hole transporting materials (TM) characterized by differential scanning calorimetry and time of flight method. The highest hole drift mobility in the newly synthesized polymers exceed 10(-4) cm(2) V-1 s(-1) at an electric field of 10(6) V cm(-1) was observed in the TM with triphenylamine moieties.
