This article summarizes the recent advance for the construction of supramolecular organic frameworks (SOFs) in aqueous media from rationally designed rigid preorganized building blocks. We first introduce the research background on the design of multitopic molecular monomers for the self-assembly of discrete supramolecular aggregates and polymers. We then describe the formation of less ordered supramolecular polymers from tritopic molecular monomers. In the following section, we show that conjugated rigid triangular building blocks have been successfully applied for the construction of two-dimensional (2D) one-layer SOFs in water. Following this, we further present the design of tetratopic building blocks for the formation of three-dimensional (3D) supramolecular networks in aqueous and organic solvents. Finally, we demonstrate that a 3D porous SOF can be assembled from a preorganized tetrahedral building block in water. For the formation of both 2D and 3D SOFs, the hydrophobically driven encapsulation of the stacked dimer of 4-phenylpyridinium unit in the cavity of cucurbit[8]uril in water plays a key role, and the dimerization of viologen radical cation has also been utilized as driving force for generating a 2D SOF. We also briefly introduce the analytical methods for the characterization of SOFs in solution. In the conclusion section, we make a perspective for the construction of SOFs in solution and their potential applications in guest adsorption and release.
