Abstract

By sacrificing a porous anodic aluminum oxide (AAO) membrane as a template, hollow tubular TpBD (H-TpBD) covalent organic framework (COF) tubes were synthesized and zeolitic imidazolate framework (ZIF-8) nanoparticles were creatively synthesized in H-TpBD tubes at room temperature. H-TpBD COF tubes and ZIF-8/H-TpBD COF tubes were procured by using a strong base or acid to remove the AAO membrane. Then they were analyzed by X-ray diffraction, Fourier infrared spectroscopy, scanning electron microscope, transmission electron microscope, Surprisingly, the obtained TpBD COF has a very small aperture (1.8 nm), thinner tube thickness (50 nm), high stability, and a smooth and homogeneous surface. And the pod-like ZIF-8/H-TpBD COF with complete tubular structure was also obtained.

摘要

通过牺牲多孔阳极氧化铝（AAO）膜作为模板，合成了中空管状的TpBD（H-TpBD）共价有机框架（COF）管，并在室温下于H-TpBD管中创造性地合成了沸石咪唑框架（ZIF-8）纳米颗粒。通过使用强碱或强酸去除AAO膜来获得H-TpBD COF管和ZIF-8/H-TpBD COF管。然后通过X射线衍射、傅里叶红外光谱、扫描电子显微镜、透射电子显微镜对它们进行分析。令人惊讶的是，所获得的TpBD COF具有非常小的孔径（1.8纳米）、更薄的管壁厚度（50纳米）、高稳定性以及光滑且均匀的表面。并且还获得了具有完整管状结构的豆荚状ZIF-8/H-TpBD COF。
