Sulfur heterocyclic aromatic hydrocarbons have the unique conductivity of benzo compounds and the unique advantages of improving conductivity and photoelectric efficiency in photosynthesis.Oligophenylene with benzothiophene structure was synthe-sized by the palladium-catalyzed Suzuki reaction of 1,3,5-tri(2-bromophenyl)benzene and benzothiophene-2-boric acid around sulfur heteropolycyclic aromatic hydrocarbons.Trithiophene twisted polycyclic aromatic hydrocarbons were synthesized by the oxi-dative dehydrogenation of oligophenylene with FeCl3.The structures of the intermediates and products were characterized by NMR and MS.The synthesis of Trisulfide heteropolycyclic aromatic hydrocarbons enriches the family of Sulfur heteropolycyclic aromatic hydrocarbons and provides a research platform for the synthesis of triple sulfur hetero twisted polycyclic aromatic hydrocarbons with larger conjugated systems.Twisted triplethiapolycyclic aromatic hydrocarbon molecules could be employed as the important candidates for organic semiconductor materials,light-emitting materials,solar cells,and photodiodes as well as other molecular de-vices.
