摘要(Abstract)：

合成温度会影响金属有机骨架(Metal organic frameworks, MOFs)的结构、孔径和产率等诸多特性。为制备高性能气体吸附MOFs薄膜，在不同介质温度(30～45℃)下采用原位生长法，在锡掺杂玻璃光波导表面制备[Zn_2-(bdc)_2-(dpNDI)]_n(Zn-MOF)薄膜；利用X射线光电子能谱(XPS)、扫描电镜(SEM)、分光光度计、椭圆偏振仪和光波导(OWG)测试系统等研究了介质温度对Zn-MOF薄膜表面形貌、光学特性(吸光度、折射率、光传播损失)及气体吸附性能的影响。结果表明：介质温度的升高有利于薄膜生长，且有效地缩短了薄膜的生长时间。介质温度在30～45℃范围内，薄膜表面形貌由球形结构转变为蜂窝状和层状结构；薄膜均透明，折射率高，光传播损失小，且对二甲苯气体表现出较大的吸附响应。40℃下生长10 h的Zn-MOF薄膜的性能最优。
