摘要:
本文以硝酸锌、对苯二甲酸(bdc)和N,N’’ -二(4-吡啶基)-1,4,5,8 - 萘二酰亚胺(dpNDI)为原料,将锡掺杂玻璃光波导作为衬底,利用原位生长法在衬底表面生长[Zn2(bdc)2-(dpNDI)]n薄膜并一步研制出[Zn2(bdc)2-(dpNDI)]n薄膜/锡掺杂玻璃光波导敏感元件;用红外光谱(IR)、高倍扫描电镜(SEM)、紫外-可见分光光度计和自组装光波导传感系统等对其结构、孔径、表面形貌、光学性质和气体吸附等特性进行研究。研究结果表明,衬底生长时间为20h、介质温度为25℃时,薄膜才能生长出完整的蜂窝式网状结构,其孔径大小平均为0.38微米。室温下,相同浓度的苯、甲苯、二甲苯、甲胺等挥发性有机气体中,[Zn2(bdc)2-(dpNDI)]n薄膜光波导对二甲苯气体的吸附响应较大,其对二甲苯气体的响应约大于其它气体响应的10倍.
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.
