Graphene-porphyrin nanohybrid materials with a direct covalent linkage between the graphene carbon network and the functional porphyrin unit have been successfully synthesized via a one-pot reductive diazotation approach. A graphite-potassium intercalation compound (KC) was dispersed in THF, and different isolated porphyrin-diazonium salts were added. The direct covalent binding and the detailed characterization of the functional hybrid material were carried out by Raman spectroscopy, TG-MS, UV/vis, and fluorescence spectroscopy. LDI-ToF mass spectrometry was introduced as a new versatile and sensitive tool to investigate covalently functionalized graphene derivatives and to establish the composition of the respective nanohybrid materials.
通过一锅还原重氮法成功合成了石墨烯-卟啉纳米杂化材料，该材料中石墨烯碳网络与功能卟啉单元之间具有直接共价键连接。将石墨-钾插层化合物 (KC) 分散在 THF 中，并加入不同的分离卟啉重氮盐。通过拉曼光谱、TG-MS、UV/vis 和荧光光谱对功能杂化材料进行了直接共价键合和详细表征。LDI-ToF 质谱被引入作为一种新的通用且灵敏的工具来研究共价功能化的石墨烯衍生物，并确定各自纳米杂化材料的组成。
