TIPS-benzene-based two-dimensional perovskites.

A novel triisopropylsilylethynyl (TIPS)-benzene-based amine and two-dimensional organic-inorganic hybrid perovskites comprising TIPS-benzene-based ammoniums are synthesized. The applicability of TIPS-based component ions to the crystal lattice of perovskites is demonstrated for the first time, promoting the development of TIPS chemistry, chemical materials that leverage TIPS moiety characteristics, and perovskite materials.
