Abstract


We report the synthesis of new 4,6-distyrylpyrimidines containing an unsubstituted carbazole ring linked with the pyrimidine moiety by a flexible aliphatic seven-membered –O(CH2)6– or –S(CH2)6– bridge. The electrochemical and spectral properties of the synthesized compounds were studied; optical band gaps were calculated from the relevant UV absorption onsets and were found to be equal to 2.55 and 2.54 eV, respectively. A thin film based on the derivative with sulfur-containing bridge (–S(CH2)6–) was deposited on a conductive material and demonstrated to have a smooth surface and hole conductivity.
