Abstract:
SUMMARY A family of benzothiophene and phenothiazine derivatives have been synthetized and characterized by Proton Nuclear Magnetic Resonance Spectroscopy and Mass Spectroscopy. Oxidation, Bromination, Alkylation and Iodination reactions have been carried out from 4,4-diphenylbromine, dibenzothiophene and phenothiazine using convergent synthesis according to yields and facilities of each reaction. The introduction of reactive functional groups as iodine and bromine in each case and alkyl chain for increase the solubility have been the main objectives of this project. 3,7-diiodobenzothiophene-S,S-dioxide,3,7-dibromobenzothiophene-S,S-dioxide and 3,7-dibromo-10-(2-ethylhexyl)-phenothiazine-5,5-dioxide are the target π-conjugated compounds which exhibit good charger transport properties according to viewed items. These aromatic compounds have been synthetized with good yields and used as starting compounds for the performance of Ullmann coupling and Buchwald–Hartwig amination reactions in order to try to obtain the last phenyl compounds which will be used for the manufacturing of optoelectronic devices.
