Ferroelectric metal-organic frameworks are emerging as an exciting field of research and have witnessed great progress in the last decade. In this contribution, we briefly discuss ferroelectricity and its means of demonstration. Three [a] in 2009. His PhD research work and patents contributed to the demonstration of the first organic ferroelectric memory array and its logic table. Following a Post-Doc period, he joined Royal Philips Electronics N. V. as a research scientist. His work at Philips was focused on the investigation of metal oxides, ferroelectrics and graphene for optoelectronic applications. In 2013, he moved to the Max-Planck Institute for Polymer Research as a senior scientist. In 2014, he was awarded the Sofja Kovalevskaja Award of the Alexander von Humboldt Foundation for his project on organic multiferroics. His current research is focused on electronic devices based on organic/inorganic hybrids. He is the coauthor of numerous papers and the holder of eight patents. Monique A. van der
