Synthesis and Properties of π-Conjugated Pyridazine and 3-Heptylthiophene Copolymer

Poly(3-heptylthiophene-alt-pyridazine) was prepared by nickel(II) complexes catalyst.(Relative) copolymer obtained by this method gives isolated yields in 75%.The copolymer was characterized by FT-IR and()~1H-NMR.The results show that the copolymer is in the structure as expected.The obtained copolymer is soluble in DMF,DMSO and CHCl_3,etc.The UV-vis spectra of the copolymer show absorption peak at 405 nm in DMSO.Photoluminescence and thermogravimetric behavior of this copolymer are also initially discussed by PL and TGA analysis.
