MARIA CHIARA DI GREGORIO, GIOVANE RICERCATRICE "RITA LEVI MONTALCINI"

Giovedì, 18 Novembre, 2021

Maria Chiara Di Gregorio ha scelto il Dipartimento di Chimica per svolgere il suo programma Rita Levi Montalcini finanziato dal MIUR per consentire ai giovani ricercatori che lavorano all’estero di venire in Italia chiamati da una Università statale per svolgere la propria attività di ricerca.

Il Direttore del Dipartimento, Luciano Galantini, è lieto di invitarvi al seminario di presentazione del programma:

Metal-organic crystal: shaping, uniformity and symmetry breaking

Abstract

The relationship between crystallization conditions, crystal structure and properties is a pivotal point in chemistry both for the investigation of fundamental aspects and for applications. The interest spans from the macro- to the nanoscale and the gamut of natural, laboratory-made, organic and inorganic systems.1 

In our study, we investigate the factors affecting the dimension and morphology of metal-organic crystals. Typically, micro-nano crystals grown by additive-free synthesis are polydispersed in size, exhibit non-homogeneous shape or common polyhedral morphologies.  We have developed a new additive-free synthesis that results in the formation of monodispersed crystals with a large variability of morphologies, while keeping the crystallographic structure nearly identical.2 The set of crystals generated include rare polyhedral shapes, hollow structures and paradoxical morphologies that are not classifiable according to conventional rules.2,3 Metal-coordination chemistry was also exploited for the formation of superstructures assembled from organic tubular crystals.4

Our work provides new fundamental insights in the growth of chiral crystals and aggregates, opening up opportunities for their use as 3D objects for nanotechnological applications.

Il seminario si terrà online martedi 23 novembre dalle ore 11.00 su piattaforma Google Meet: https://meet.google.com/evx-vvne-seh
