    This study explores spin-crossover (SCO) molecules for molecular magnetism and electronic devices. A new example, [Fe(neoim)2], is introduced, demonstrating both bulk and thin-film capabilities. The material's synthesis, magnetostructural characterization, and high-vacuum sublimation for thin-film formation are investigated. Retention of spin-crossover capabilities, including a rapid light-induced spin transition (LIESST effect) in ultrathin films (15 nm), is observed through X-ray absorption spectroscopy.

  • Porphyrin-fused graphene nanoribbons

    Authors: Qiang Chen, Alessandro Lodi, Heng Zhang, Alex Gee, Hai I. Wang, Fanmiao Kong3, Michael Clarke, Matthew Edmondson, Jack Hart, James N. O’Shea, Wojciech Stawski, Jonathan Baugh, Akimitsu Narita, Alex Saywell, Mischa Bonn, Klaus Müllen, Lapo Bogani & Harry L. Anderson

    This study reports the solution-phase synthesis of porphyrin-fused graphene nanoribbons (PGNRs) featuring metalloporphyrins, demonstrating long chains, a narrow optical bandgap, and high charge mobility. PGNRs enable the fabrication of ambipolar field-effect transistors and single-electron transistors, offering a pathway to engineer electrical and magnetic properties in nanostructures through porphyrin coordination chemistry.
