Abstract:

Spectroscopic and photophysical properties of the poly(azomethine)s with triphenylamine moieties were investigated by UV–vis, X–ray diffraction and atomic force microscopy methods. Current–voltage measurements were performed on ITO/polymer/Alq 3/Al, ITO/PEDOT/polymer:MWCNT/Al and ITO/polymer:MWCNT/Al devices. Multiwall carbon nanotubes were blended with polymer in the ratio 1:1. The lowest optical band gap value at 2.33 eV was detected. Moreover, an absorption coefficient α was calculated from transmission and reflectivity measurements. In this paper, we presented photophysical and structural properties of the poly(azomethine)s in solid state of great interest for the emerging field of molecular electronics and for their uses as active layers in (opto)electronic devices such as solar cells.
