Özet
Polyazomethines including perylene units in the main chain were synthesized via polycondensation of diaminoperylene with aromatic dialdehydes. UV/vis, FT-IR, H-1 NMR, C-13 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 (M-n), weight-average molecular weight (M-w) 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 (E-g') and optical (E-g) hand 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.
