Abstract
Polyazomethines including perylene units in the main chain were synthesized via polycondensation of diaminoperylene with aromatic dialdehydes. UV/vis, FT-IR, 1H NMR, 13C NMR and elemental analysis techniques were carried out for the characterization of the synthesized diaminoperylene, dialdehydes and polyazomethines including perylene units (PAM-PERs). The number-average molecular weight (Mn), weight-average molecular weight (Mw) and polydispersity index (PDI) values of PAM-PERs were determined by size exclusion chromatography (SEC). Thermal properties of PAM-PERs was determined by using TGA/DTA and DSC systems. The highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital (LUMO) energy levels, and electrochemical (Eg′) and optical (Eg) band gap values were calculated by using the results of cyclic voltammetry and UV/vis, respectively. Conductivity measurements of PAM-PERs were carried out with electrometer by using four-point probe technique. The conductivity was observed to be increased by doping agent iodine.
