Poly(ethylene oxide)/teraamino-phthalocyanine copper (II) (PEO/(NH2)(4)PcCu) 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)(4)PcCu molecule was successfully embedded in the one-dimensional hybrid nanofibers via chemical interaction between PEO and (NH2)(4)PcCu. The PL results showed that the PEO/(NH2)(4)PcCu hybrid nanofibers had an intense emission at about 450 nm. A possible PL mechanism was proposed accordingly. (c) 2007 Elsevier, Ltd.
