Synthesis and Characterisation of Hole Transporting Materials Based on N,N,N-Tris- [4-(Naphthalen-1-yl-phenylamino)Phenyl]-N,N,N-Triphenylbenzene-1,3, 5-Triamine

Two derivatives of star shaped compounds based on naphthylamine with symmetric trisubstituted benzene as core, methoxy and ethoxy as end substitutions are synthesized. The synthesized compounds are characterized by UV-visible, FT-IR and NMR spectrometric techniques. The electronic and thermal properties of the compounds are studied using cyclic voltametry (CV) and differential scanning calorimetry (DSC) respectively. The data's obtained have similarity with the arylamines that have been already used in optoelectronic devices. So these compounds are interesting materials for applications in such devices
