Two-dimensional (2D) layered standard ABX3 cubic halide perovskite is being actively studied because it has many advantages, such as solution processability, extensive structural and property tunability, and excellent optoelectronic properties. By tuning the ‘A’ cations in the perovskite, it is possible to achieve high-performance in electronic devices. Indole and phthalimide have high thermal stability and excellent charge carrier mobility. In addition, it is possible to introduce various substituents to nitrogen, which allows tuning of solubility and molecular packing. In this study, we designed and synthesized novel organic cations for 2D layered halide perovskites based on thiophene-incorporated indoles and phthalimides. The properties of the perovskite film made of synthesized cations were observed under various conditions. Crystalline properties were observed through UV-vis and XRD analysis, and electrical properties were confirmed by fabricating FETs. |
