Electrically Conductive Metal-Organic Framework Thin Films
Conducting metal?organic frameworks (MOFs) present a compelling prospect for the development of high-performance electronic devices, ranging from electrocatalysts to supercapacitors. However, realizing their full potential requires overcoming challenges, particularly in controlling the macroscopic morphology of MOFs for seamless integration into practical applications. This presentation introduces two methods for synthesizing a conductive two-dimensional MOF thin film: one via a single-step, all-vapor-phase chemical vapor deposition (CVD) process, and the other through a solution-processable synthetic approach. The large-area thin film of Cu3(C6O6)2 synthesized with CVD has high crystallinity and an edge-on-orientation. Microdevices based on Cu3(C6O6)2 thin film were fabricated using e-beam lithography, and the thin film exhibited an electrical conductivity of 92.95 S/cm. The synthesis of conductive MOF thin films through all-vapor-phase CVD could provide insights into the physical properties of these materials and pave the way for practical applications.
