Organic ferroelectric materials are in demand in the growing field of
environmentally friendly, lightweight electronics. Donor-Acceptor charge
transfer crystals have been recently proposed as a new class of organic
ferroelectrics, which may possess a new kind of ferroelectricity, the so-called
electronic ferroelectricity, larger and with faster polarity switching in
comparison with conventional, inorganic or organic, ferroelectrics. The current
research aimed at achieving ambient conditions electronic ferroelectricity in
organic charge transfer crystals is shortly reviewed, in such a way to evidence
the emerging criteria that have to be fulfilled to reach this challenging goal.Comment: 6 pages, 7 figures. Proceedings of "2018 SUSTAINABLE INDUSTRIAL
