Inside Cover: Sequential Logic Operations with Surface-Confined Polypyridyl Complexes Displaying Molecular Random Access Memory Features (Angew. Chem. Int. Ed. 1/2010)
Redox-active monolayers form the basis of a solid-state setup that is able to mimic the input/output characteristics of electronic circuits. In their Communication on page 169 ff., M. E. van der Boom and co-workers demonstrate sequential logic operations controlled by multiple chemical inputs, with one circuit equivalent to a set–reset latch—one of the fundamental parts in random access memory. The kind of logic (combinatorial or sequential) can be controlled by keeping the current state static or dynamic.
