Synthesis and characterisation of hole transporting soluble polyschiff base containing triarylamine unit in the backbone

A soluble polyschiff base containing triarylamine unit in backbone was synthesised by condensation polymerisation. The hole transport properties of such polyschiff base were studied. The mobility of the hole carrier in the polyschiff base film was also measured and found to be μ=1.68×10−4cm2/Vs by means of time of flight technique. A polymer electroluminescence device was prepared with the polyschiff base used as hole transporting moiety by spin coated.
