Abstract

An organic polymeric fluorophore, s-triazine (ST) bridged p-phenylenevinylene (PPV), was explored for a thin film sensor. The ST-PPV showed fluorescence intensity in response to the polarity of organic molecules. The fluorophore was doped in transparent polymeric binder to prepare a thin film sensor. Fluorescence intensity of the thin film sensor was dramatically changed by the polarity change of the organic vapor. Addition of titanium dioxide nanoparticles into the polymer thin film sensor enhanced dramatically the fluorescence intensity. The nanoparticle doped fluorescent thin film sensor showed large change in intensity upon exposed to different organic molecules.
