Photoluminescence and electrochemistry behavior of well-dispersible poly-N-[5-(8-quinolinol)ylmethyl]aniline/nano-TiO2 composite

Well-dispersible poly-N-[5-(8-quinolinol)ylmethyl]aniline/nano-TiO2 composite was synthesized by the surface modification of nano-TiO2 particles using poly-N-[5-(8-quinolinol)ylmethyl] (PANQ), and it was characterized by Fourier-transform infrared spectroscopy, photoluminescence spectroscopy, thermogravimetric analysis and scanning electron microscope, as well as conductivity and cyclic voltammogram were given. The conductivity of this composite was 2.1 x 10-2 S cm-1 at 25 deg. C, and showed good redox reversibility. It was easy to cast a transparent conducting film with photoluminescent property
