Two new phenothiazine – based structures, including 4-(10H-phenothiazin-10-yl)-N,N-diphenylaniline (PDA) and 10-(pyren-1-yl)-10H-phenothiazine (PyP) were synthesized via Buchwald-Hartwig C-N coupling amination using catalytic palladium modulated by electron-rich ligands. Chemical structures were analysed via proton nuclear magnetic resonance (1H NMR) spectroscopy. Then, photo-properties were characterized by UV – Vis absorption spectroscopy in various concentrations of each product. The results showed that PDA and PyP are highly potential donor units for well-performed donor – acceptor conjugated polymers.
