Assembling Dimeric π Stacks on Gold Surfaces by Using Three‐Dimensional Lock‐and‐Key Receptors

Nest building: a method to create a rigid hydrogen-bond receptor through the simultaneous binding of three thiol substituent groups to a gold surface is reported (see picture: red=O, gray=C, blue=N, yellow=S, purple=Au surface atom). These receptors are able to distinguish and select for π surfaces with a complementary size, shape, and hydrogen-bonding code.
