From molecules to materials: structure-property correlation in functional materials Functional molecular materials are at the heart of emerging technologies in sensing, optoelectronics, and smart materials. Their macroscopic properties often result from collective phenomena in the solid state, making their rational design both complex and rewarding. This seminar will focus on the development and understanding of such materials through a multidisciplinary approach combining synthesis, quantum crystallography, and theoretical modeling. A central theme will be the exploration of structure–property relationships in the crystalline phase, with emphasis on how non-covalent interactions drive self-assembly and control photophysical properties. Luminescent materials exhibiting aggregation-induced emission (AIE) will be presented as model systems, alongside pressure-responsive systems showing pressure-induced emission enhancement (PIEE).

Crossing the Border - Structural Chemistry around the Zintl Line Alkali metal Zintl phases can be traced back to the investigative works of Eduard Zintl himself, who reported on the structural characterization of textbook-known sodium thallide (NaTl) already in 1932. Interestingly, thallium, as a group 13 element, is located to the left of the so-called Zintl line, which separates the p-block elements concerning the formation of either salt(-like) or metallic compounds in intermetallic materials of the alkali or alkaline earth metals. In my talk, we will cross the Zintl-line. Solution and crystallization studies of group 14 element Zintl salts in liquid ammonia will be introduced.
