\r\n
\r\nSince Pasteur's discovery of molecular chirality, understanding how molecular handedness couples to its physical environment has remained a fundamental challenge. Of particular interest is its interplay with magnetism, anticipated already by Pierre Curie in 1894, as well as the emergence and propagation of chirality through molecular organization. Here, we explore these connections at surfaces, from the interaction of individual chiral molecules with magnetic substrates and spin-polarized electrons to the collective organization of molecular chirality in extended two-dimensional structures. First, we demonstrate enantioselective adsorption of individual helicene molecules on ferromagnetic cobalt surfaces. Spin- and chirality-resolved scanning tunneling microscopy reveals that left- and right-handed helicenes preferentially adsorb on Co islands with opposite out-of-plane magnetization, establishing a direct correlation between molecular handedness and substrate magnetization. Second, tunneling-conductance measurements through individual enantiomers reveal magnetochiral asymmetries of up to 50%, demonstrating spin-selective electron transport at the single-molecule level and excluding ensemble effects as the sole origin of chirality-induced spin selectivity (CISS). Finally, we report the first observation of aperiodic chiral molecular tiling arising from topological self-assembly on a silver surface, demonstrating how molecular chirality can propagate from individual building blocks into complex collective organization.","image_description":"","creation_date":"2026-10-01T19:17:53","last_modification_date":"2026-10-02T08:39:11","link_label":"","link_url":"","canceled":"False","cancel_reason":"","place_and_room":"CH G1 495","url_place_and_room":"https://plan.epfl.ch/?room==CH%20G1%20495","url_online_room":"","spoken_languages":["https://memento.epfl.ch/api/v1/spoken_languages/2/?format=json"],"speaker":"Karl-Heinz Ernst (EMPA)","organizer":"Sascha Feldmann","contact":"sascha.feldmann@epfl.ch","is_internal":"False","theme":"","vulgarization":{"id":2,"fr_label":"Public averti","en_label":"Informed public"},"registration":{"id":3,"fr_label":"Entrée libre","en_label":"Free"},"keywords":"pcseminar","file":null,"icalendar_url":"https://memento.epfl.ch/event/export/122021/","category":{"id":1,"code":"CONF","fr_label":"Conférences - Séminaires","en_label":"Conferences - Seminars","activated":true},"academic_calendar_category":null,"domains":[],"mementos":["https://memento.epfl.ch/api/v1/mementos/5/?format=json","https://memento.epfl.ch/api/v1/mementos/14/?format=json"]},{"id":72737,"title":"PChem Seminar - Adriana Pietropaolo","slug":"pchem-seminar-adriana-pietropaolo","event_url":"https://memento.epfl.ch/event/pchem-seminar-adriana-pietropaolo","visual_url":"https://memento.epfl.ch/image/33982/200x112.jpg","visual_large_url":"https://memento.epfl.ch/image/33982/720x405.jpg","visual_maxsize_url":"https://memento.epfl.ch/image/33982/max-size.jpg","lang":"en","start_date":"2026-11-12","end_date":"2026-11-12","start_time":"17:00:00","end_time":"18:00:00","description":"Theory-Guided Design of Chiral Hybrid Perovskites
\r\n
\r\nChiral halide perovskites combine the outstanding optoelectronic properties of the inorganic
\r\noctahedra with the chirality of the organic cations, enabling control over light polarization and electron
\r\nspin1. This makes them promising platforms for spin-optoelectronics and quantum technologies2,3.
\r\nDesigning them rationally, however, requires understanding how chirality is transferred from the
\r\norganic cations to the inorganic framework, and how this transfer governs their chiroptical and spin
\r\nproperties4.
\r\nIn this seminar I will present a simulation framework that combines ab initio molecular dynamics, freeenergy
\r\nmethods and time-dependent density functional theory to predict circular dichroism (CD),
\r\ncircularly polarized luminescence (CPL), absorption and emission dissymmetry factors (gabs, glum) in
\r\nchiral perovskites. Applied to (R/S-MBA)2PbI4 and its tin analogue, this approach shows that
\r\nenantiomeric excess acts as a continuous dial for chiroptical properties5. The response follows a
\r\ncooperative majority-rule mechanism, which we validated against experiments across the full
\r\nenantiomeric series. Electronic-structure analysis links the two characteristic CD bands to distinct
\r\nband-edge and organic–inorganic transitions.
\r\nI will also discuss how chemical strain and hydrostatic pressure can tune the intensity and sign of CPL
\r\nemission6, and how structural chirality, spin-orbit coupling and lattice distortions may shape spin
\r\npolarization. Together, these results outline predictive design rules for chiral perovskites with tailored
\r\noptical and spin functionalities.
