Electrospun nanofibers of poly(ethylene oxide)/teraamino-phthalocyanine copper(II) hybrids and its photoluminescence properties Original Research Article

Poly(ethylene oxide)/teraamino-phthalocyanine copper (II) (PEO/(NH2)4PcCu) hybrid nanofibers with a diameter of 200–300 nm were prepared by electrospinning technique. The hybrid nanofibers membrane was characterized by scanning electron microscopy (SEM), Fourier transform infrared (FT-IR), ultraviolet–visible (UV–vis), and photoluminescence (PL), respectively. The results indicated that (NH2)4PcCu molecule was successfully embedded in the one-dimensional hybrid nanofibers via chemical interaction between PEO and (NH2)4PcCu. The PL results showed that the PEO/(NH2)4PcCu hybrid nanofibers had an intense emission at about 450 nm. A possible PL mechanism was proposed accordingly.
