In this work, two novel hyperbranched conjugated polymers poly(tris(4-(10-(2-ethylhexyl)-10H-phenoxazin-3-yl)phenyl)amine) (P1) and poly(tris(4-(7-(benzo[c][1,2,5]thiadiazol-4-yl)-10-(2-ethylhexyl)-10H-phenoxazin-3-yl)phenyl)amine) (P2) have been successfully synthesized via Direct polycondensation in the presence of Pd(OAc)2 as a catalyst. The chemical structures then were determined Fourier-transform infrared spectroscopy (FTIR) proton nuclear magnetic resonance (1H NMR). Subsequently, optical properties different solvents investigated UV–Vis absorption fluorescence emission (PL) spectroscopies, analyzed for optoelectronic applications.
