Abstract:

Several types of molecular connectors have been synthesized and used for the preparation of two kinds of regular two-dimensional molecular grids on liquid surfaces. The connectors are connected into square or hexagonal networks by hydrogen-bonding couplers such as hydroquinones or by mercury cations. The electrochemistry, spectroscopy, and scanning tunneling imaging of the structures have been investigated, and in some cases extensive long-range order was observed. In addition, the relation between the conformation of saturated linear silicon chains and their electronic states have been investigated by methods based on photophysics, spectroscopy, and quantum theory.
