The synthesis of the mono-, di- and tri-(trityloxy) triazine by the interaction of cyanuric chloride with triphenylmethanol in tetrahydrofuran or acetone in the presence of sodium carbonate is reported. These compounds were characterized by elemental analysis, IR, UV-Vis, mass and NMR spectra. The correlation between semiconducting properties such as electrical conductivity and energy band gap width with the molecular structure of the prepared compounds is established. The energies band gap are 3.85, 3.76 and 3.4 eV. Our study was performed in the temperature range 293–453 K. The results show that the prepared compounds have semiconducting properties which is confirmed by the calculated band gap energies, whereas the activation energies calculated from the Arrhenius equation have the values 0.163, 0.152 and 0.140 eV respectively.
