Abstract

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 of novel conjugated polymers then were determined via Fourier-transform infrared spectroscopy (FTIR) and proton nuclear magnetic resonance (1H NMR). Subsequently, the optical properties of conjugated polymers in different solvents were investigated via UV–Vis absorption and fluorescence emission (PL) spectroscopies, and were analyzed for optoelectronic applications.
