Conducting poly-N-[5-(8-quinolinol)ylmethyl]aniline/nano-SiO2 composite with fluorescence

A conducting poly-N-[5-(8-quinolinol)ylmethyl]aniline/nano-SiO2 composite with fluorescence was obtained by surface modification of nano-SiO2 particles using poly-N-[5-(8-quinolinol)ylmethyl](PANQ), and was characterized by Fourier-transform infrared spectra, UV–vis absorption spectra, fluorescence spectra, thermogravimetric analysis and transmission electron microscopy, as well as conductivity. The conductivity of this composite was 2.72 × 10− 2 S cm− 1 at 25 °C, which contained approximately 50% PANQ. It can potentially be used in commercial applications as a conducting film with PL property.
