Chemical Soldering Process

An STM tip applies a voltage, initiating polymerization of the diacetylene groups in surface-bound carboxylic acid molecules (black and red). The polymerized wire (yellow) propagates until it bumps against a single phthalocyanine molecule (blue) in a cluster. A bond forms, and the completed "circuit" is shown in an STM image.
