{Reference Type}: Journal Article {Title}: Toward Molecular Cybernetics - the Art of Communicating Chemical Systems. {Author}: Schmittel M;Howlader P; {Journal}: Chem Rec {Volume}: 0 {Issue}: 0 {Year}: Dec 2020 17 {Factor}: 6.935 {DOI}: 10.1002/tcr.202000126 {Abstract}: The emerging field of molecular cybernetics has the potential to widely broaden our perception of chemistry. Chemistry will develop beyond its current focus that is mainly concerned with single transformations, pure compounds, and/or defined mixtures. On this way, chemistry will become autonomous, networked and smart through communicating molecules each of which serves a control engineering purpose, like the set of wheels in the machinery of life. The present personal account describes our latest developments in this field.
