| Abstract Scope |
In two-dimensional materials, solid-state chemistry and surface functionalization chemistry can be married to create materials with unique electronic, optoelectronic, and catalytic properties that can be tailored via chemical design. Here, we describe the synthesis, structure, and properties of novel families of layered hybrid organic/inorganic 2D materials that can be prepared via the topotactic deintercalation of solid-state lattices. First, we will discuss our long-standing efforts in organic-terminated germanium graphene analogues, prepared from CaGe2. Second, we will describe a new hybrid 2D material system with the stoichiometry of A2Ni3Ch4 (A = R-NH3+; M = Ni; Ch= S, Se), and comprised of anionic, layered, porous honeycomb networks of perpendicularly oriented NiCh42- square planes, separated by organic cations. For both material families, we will establish how the electronic and optoelectronic properties can be chemically tailored. Finally, we highlight how the identity of the surface ligand can lead to unexpected interactions with the chemical environment. |
