摘要：在本论文中，我们以金属卟啉分子作为结构单元构建卟啉复合物薄膜。金属卟啉的结构易于调节，且具有很好的热稳定性和化学稳定性，在光电器件、催化等领域都有广泛应用。本文设计合成了一种能在三文方向自导向组装的笼形倍半硅氧烷修饰的新型钴卟啉单体。利用这种单体的结构特点，通过共轭双齿桥联配体，1,2-二吡啶乙炔分子诱导，促使单体定向排列并在三文方向上进行自导向组装，构建有序的卟啉复合物薄膜。经过X射线衍射 (XRD)，高分辨率透射电子显微镜 (HRTEM)，红外光谱 (FT-IR)，紫外-可见分光光度计 (UV-Vis)，X射线光电子能谱 (XPS) 和全自动比表面分析仪 (BET)对该复合薄膜的结构及性质进行了表征。结果表明，1,2-二吡啶乙炔分子已与硅烷化钴卟啉单体中心的Co(Ⅲ) 离子成功配位构建有序卟啉金属有机框架化合物薄膜，而且该三文有序的卟啉复合薄膜展现了优越的光电性质。39021

Preparation and photoelectric properties of porphyrin composite films
Abstract:  In this paper, we used metalloporphyrin molecules as assembly units. Because its structure is easy to be modulated, and metalloporphyrins with high thermal and chemical stability have showed a wide range of applications in optoelectronic devices, catalysis. We designed and synthesized a novel porphyrin cobalt monomer, which has a potential self-directed assembly ability in three-dimensional directions. We built stable and orderly porphyrin composite thin films by self-directed assembly of this porphyrin cobalt monomer. This materials were well-ordered and mesoporous, a series of samples was examined by powder X-ray diffraction (XRD), High-resolution transmission electron microscopy (HRTEM), FT-Raman spectroscopy (FT-IR), Solid UV-visible absorption spectra (UV-Vis), X-ray photoelectron spectroscop (XPS), Brunauer-Emmett-Teller (BET). Together these data demonstrate that 1,2-bis(4-pyridy)acetylene (Bpa) has been incorporated into the central Co(III) ion of the SPCM and successful fabricated the highly oriented porphyrin metal-organic framework films. This networks with broad pore-size distribution promises access to an even wider range of application possibilities. Specially， This threedimensional ordered porphyrin films display excellent photo-electronic performance.
