In this research, the new fluorescent conjugated polymers based on 10-(Perylene-3-yl-10H-Phenoxazine (PyP) and 9,9-dioctyl-9h-fluorene (PF) have been synthesized via direct arylation polymerization using Pd(OAc)2, PivOH and PCy3.HBF4 as catalyst system. The monomer based on phenothiazine has been synthesized via C-N coupling to obtain the 4-(10H-phenothiazine-10-yl)-N,N-diphenylaniline (PyP). The synthesized novel conjugated polymers based on PyP and PF have been characterized via 1H NMR, GPC, FTIR, DSC, XRD, PL, and UV-Vis spectrum. The obtained conjugated polymers exhibited a narrow bandgap of 2.85 eV and polymer exhibited the fluorescent emission at 350 nm. Based on the optical properties of PFPyP polymer, PFPyP can be applied for organic solar cell and fluorescent chemosensor devices.
