Two series of organic–inorganic composite materials were synthesized through solvothermal imine condensation between diketopyrrolopyrrole dialdehyde DPP-1 and 5,10,15,20-tetrakis(4-aminophenyl)porphyrin (TAPP) in the presence of varying amounts of either amino- or carboxy-functionalized superparamagnetic iron oxide nanoparticles (FeO). Whereas high FeO loading induced cross-linking of the inorganic nanoparticles by amorphous imine polymers, a lower FeO content resulted in the formation of crystalline covalent organic framework domains. All hybrid materials were analyzed by magnetization measurements, powder X-ray diffraction, electron microscopy, IR, and UV/Vis absorption spectroscopy. Crystallinity, chromophore stacking, and visible absorption features are directly correlated to the mass fraction of the components, thus allowing for a fine-tuning of materials properties.

通过在二酮吡咯并吡咯并二醛DPP-1和5,10,15,20-四（4-氨基苯基）卟啉（TAPP）之间的溶剂热亚胺缩合反应合成了两种有机-无机复合材料。羧基官能化的超顺磁性氧化铁纳米粒子（FeO）。而高的FeO诱导的交联无定形的亚胺聚合物的无机纳米粒子，低级装载的FeO含量导致形成结晶共价有机骨架结构域。通过磁化测量，粉末X射线衍射，电子显微镜，IR和UV / Vis吸收光谱对所有杂化材料进行了分析。结晶度，生色团堆积和可见吸收特征与组分的质量分数直接相关，因此可以对材料特性进行微调。
