In this report, I will introduce several families of 2D organic topological insulators (OTIs), based on first-principle density functional theory calculations. Firstly, I will talk about the construction of the 2D metal organic frameworks. Secondly, I will introduce several intrinsic 2D OTIs in the 2D π-conjugated covalent-organic frameworks. In the end, by using the electron counting and crystal field theory, I will explain the origin of the intrinsic topological properties in the 2D π-conjugated covalent-organic frameworks.
