Ferroelectric metal-organic frameworks

Ferroelectrics are polar materials whose polarization direction can be switched by applying an electrical field. They can therefore exist in two states that can be assigned to 1’s and 0’s of a binary system, and as such they can serve as memory platforms in electronic devices. However, ferroelectric materials are typically inorganic compounds with a high processing temperature, which makes them incompatible with the emerging generation of flexible electronics. Organic ferroelectrics have milder processing conditions, but so far suffer from low polarizations and low Curie temperatures (temperature above which the ferroelectricity disappears). 

New ferroelectric materials are urgently needed in order to fulfill the requirements of future technologies. Yet, their identification is largely based on trial-and-error. In contrast, our research uniquely aims to develop a class of materials whose ferroelectric properties can be systematically altered and improved: ferroelectric metal-organic frameworks.

Metal-organic frameworks (MOFs) are crystalline materials in which inorganic ions are connected by organic molecules, thus comprising a 3-D framework. Their well-known structures and mild synthesis conditions—among several other attractive qualities—make them an excellent platform for the rational design of a new class of ferroelectrics.
