Studies on Dielectric, Super-Capacitive and Photoluminescence Properties of Metal Organic Frameworks Subjected to Varying Temperature and Frequencies

Abstract

Metal organic frameworks when subjected to varying temperatures and frequencies. The analysis indicate the presence of guest molecules enhance the dielectric constant. The dielectric constant increase to a limit with the rise in temperature but it reduces gradually. The increase in frequencies enhance the peaks of permittivity towards higher temperatures. Shortening of ion diffusion also enhances the capacitance and a better contact between the electrode and active substance increases the electrochemical performance. Luminescence, the color depends on particle size, the structure and intermolecular packing of atoms in material. This paper gives an overview of MOFs studied based on their dielectric, super-capacitive and photo-luminescence when subjected to varying temperatures and frequencies.
