Synthesis of copper(I) catenanes incorporating a disulfide bridge and their deposition on a gold surface

GRAPHICS The synthesis of two coordinating catenates with the ability to undergo surface-confined chemistry is described, For each catenate, one of the rings includes a 2,9-diphenyl-1,10-phenanthroline unit as a coordinating moiety and a disulfide bridge, which allows adsorption of the catenate onto a gold surface, thus going from a molecular catenate to a [gold adsorbed] species in which gold atoms are elements of one of the rings.
