Atomic‐scale mechanochemistry is realized from force exerted by a C 60 ‐functionalized scanning tunneling microscope tip. Two conformers of tin phthalocyanine can be prepared on coinage‐metal surfaces. A transition between these conformers is induced on Cu(111) and Ag(100). Density‐functional calculations reveal details of this reaction. Because of the large energy barrier of the reaction and the strong interaction of SnPc with Cu(111), the process cannot be achieved by electrical means.
