中文摘要：

减少的 graphene 氧化物(RGO ) 是 covalently 有由二个方法的卟啉一半的 functionalized：直接 Prato 反应(即 1,3-dipolar cycloaddition ) 与 sarcosine 和包含甲酰的卟啉，并且用 4-hydroxybenzaldehyde 包含 1,3-dipolar cycloaddition 到 RGO 表面的一个逐步的方法，与适当卟啉由亲核的替换列在后面。到 RGO 表面的卟啉的化学结合被紫外 / 可见的吸收证实了，荧光， Fourier 变换红外线，并且拉曼光谱学， X 光检查粉末衍射和 X 光检查光电子光谱学，传播电子和原子力量显微镜学，和 thermogravimetric 分析；这个化学附件保证在 RGO 和卟啉之间的有效电子 / 精力转移，并且 RGO 先锋和太古的卟啉与那些相比负担得起改进光非线性。

英文摘要：

Reduced graphene oxide （RGO） has been covalently functionalized with porphyrin moieties by two methods： A straightforward Prato reaction （i.e. a 1,3-dipolar cycloaddition） with sarcosine and a formyl-containing porphyrin, and a stepwise method that involves a 1,3-dipolar cycloaddition to the RGO surface using 4-hydroxybenzaldehyde, followed by nucleophilic substitution with an appropriate porphyrin. The chemical bonding of porphyrins to the RGO surface has been confirmed by ultraviolet/visible absorption, fluorescence, Fourier-transform infrared, and Raman spectroscopies, X-ray powder diffraction and X-ray photoelectron specfroscop）~ transmission electron and atomic force microscopy, and thermogravimetric analysis; this chemical attachment assures efficient electron/energy transfer between RGO and the porphyrin, and affords improved optical nonlinearities compared to those of the RGO precursor and the pristine porphyrin.
