Poly-o-toluidine (POT) was chemically and electrochemically synthesized for the study of the electronic and steric effect of methyl substituents. It was found that the steric effect was dominant in POT. The IP 4.95 eV, EA 3.24 eV, Eg 1.71 eV of POT were found by the CV (Cyclic Voltammetry) and CCPSA (Constant Current Potentiometric Stripping Analysis).

Poly-o-toluidine (POT) was chemically and electrochemically synthesized for the study of electronic and steric effect of methyl substituents. The turn-on voltage of organic light emitting diode (OLED) was 9~14 V. ITO/POT/Al structured OLED were fabricated with various oxidation states of POT. PL, I-V characteristics and EL spectra were investigated.
