Abstract:: In this paper, [Zn2(bdc)2-(dpNDI)]n thin films were fabricated by In-situ growth method. The zinc nitrate, terephthalic acid (bdc) and N-N ’’- dianiline 4-pyridyl 1,4,5,8 -naphthalenediimide (dpNDI) were used as precursors, the tin-diffused glass waveguide was used as substrate, and was immersed in [Zn2(bdc)2 -(dpNDI)]n precurse solution for 5,10,15,20 and 25 h, at room temperature. The infrared spectroscopy (IR), high power scanning electron microscopy (SEM), UV-Vis spectroscopy and self-assembled optical waveguide sensing system were employed to investigate the structure, pore size, surface morphology ,optical properties and gas adsorbility of [Zn2(bdc)2-(dpNDI)]n thin films. The experimental results indicates that, while immersion for 20 h at the room temperature, the [Zn2(bdc)2-(dpNDI)]n thin film optical waveguides exhibit greater adsorption response to xylene gas, and the response of xylene gas is more greater 10 times than that of other gases.
