Molecular interfaces formed between metals and molecular compounds have enormous potential as building blocks for future opto-electronics and spin-electronics devices. Transition metal phthalocyanine and porphyrin complexes are promising components for such interfaces. Scientists at Forschungszentrum Jülich, together with a team of international scientists, have been working to develop a model system for designing such devices with unique functions and enhanced performance by stabilizing and controlling the spin and oxidation states in the complexes with nanoscale precision. Among other things, they discovered a mechanism that can be used in the future to store information in porphyrins or to develop extremely sensitive sensors to detect toxic nitrogen dioxide.
