Within DIPC International Physics Colloquia initiative, outstanding guest speakers covering all areas of natural science are invited every month or so to deliver colloquium-style talks.
Scope & aim
The intended audience of DIPC colloquia are all interested scientists at DIPC and neighboring institutes, from PhD student to Professors.
Colloquium speakers are encouraged to give broadly accessible talks with emphasis on providing an overview and general ideas of their research field as well as a personal view of the open questions, grand challenges, and future research directions.
DIPC colloquia are primarily addressed to scientists and may thus contain specialized and technical material, but they are open to anyone interested in science.
Coordinates & format
Colloquia are held in the "Josebe Olarra" DIPC's Seminar Room (building 1, DIPC headquarters) and generally scheduled on Thursday afternoons. The duration of the talk is about one hour. DIPC offers refreshments afterwards to make occasion to meet the speaker and other colleagues and discuss the presentation.

PhD Thesis defense: Spin Interactions in Organic Molecular Architectures

10:00 | Sala de Actos de la Facultad de Química
This thesis investigates spin interactions in atomically precise organic nanostructures synthesized on metal substrates using on-surface synthesis techniques. While magnetism is usually associated with transition metals, it can also emerge in light elements like carbon through π-magnetism, driven by unpaired p-shell electrons. Magnetic carbon-based nanostructures are expected to exhibit unique properties such as enhanced spin delocalization and long coherence times, making them promising candidates for spintronics and quantum information applications. We employ scanning probe microscopy techniques—mainly scanning tunneling microscopy (STM) and spectroscopy (STS)—along with theoretical simulations to study various organic systems with differing numbers of unpaired π electrons: a non-planar organic diradical (2-OS); a triradical nanographene (TTAT), formed by joining three [3]triangulenes via a nitrogen-doped triangulene core; and a [3]triangulene-based macrocycle (TNS), accumulating twelve unpaired electrons. Finally, we explore strategies for fabricating two-dimensional covalent networks using open-shell triangulene units, with the aim of creating extended organic spin architectures.
