Wrocław University of Science and Technology Physics Seminar – Monday 19th of January 2026
We cordially invite you to Wrocław University of Science and Technology Physics Seminar on Monday 19th of January 2026 at 11:15 in room 322, building A-1, where there will be delivered a lecture:
Non-Covalent Interactions as a Driving Force for Polar Phases in Organic–Inorganic Ferroelectrics

Hybrid molecular ferroelectrics represent a rapidly developing class of functional materials that combine facile synthesis, cost-effectiveness, and highly tunable electrical and optical properties. The seminar will address challenges related to the rational design of such compounds, arising from the complex interplay between molecular and inorganic components that governs structural phase transitions and atomic arrangements. Emphasis will be placed on the role of non-covalent interactions in stabilizing polar phases, with particular attention given to the impact of hydrogen bonding on the flexibility and dynamic behavior of inorganic anions. It will be demonstrated how order–disorder processes associated with molecular reorientation induce distortions of the anionic substructure and control symmetry, packing, and ferroelectric ordering.
The presentation will include recent results on phase transitions in halo-metalates, characterized by complex phase diagrams and incommensurately modulated structures. In addition, organically templated metal–oxalate coordination polymers exhibiting water-dependent ferroelectric switching and multiferroic behavior, confirmed by magnetoelectric coupling, will be discussed.
The seminar will be of interest to researchers working in condensed matter physics, crystallography, materials science, and solid-state chemistry, as well as to students interested in structure–property relationships in hybrid functional materials.
