a Molecular structure of complex 1. b Thermal evolution of the optical reflectivity (λ = 452 nm) of a 200-nm-thick film of 1 on top of a gold microwire (2 mm × 2 µm × 300 nm) after 1, 104, 105, 106, and 107 thermal cycles in air induced by Joule heating. These data show the large variation of the reflectivity due to the molecular spin-state switching and demonstrate the exceptionally high resilience of the spin transition over 107 thermal cycles. Time evolution of c the applied electrical current, d the wire temperature, and e the optical reflectivity on the wire recorded simultaneously at selected times of the thermal-cycling experiment using the Joule-heated microwire.
