Molecular Wires

Molecular Wires. The search of a molecular based system exhibiting adequate electrical conductance and good structuring problems is a main goal in molecular electronic. Coordination polymers (CPs) are good candidates for to full fill these requirements. We have develop several techniques to fabricate highly conductive nanostructures  based on CPs (more..).

One approach is based on direct sublimation of CPs crystals. By controlling the temperature and the evaporation rate for very low concentrated solutions of MMX polymers seems to be a viable alternative. This strategy results in the formation of uniform nanocrystals on surfaces by drop casting. The so-formed structures present thickness and width smaller than these obtained by direct sublimation of the polymer crystals.

Additionally, we have explored the use of lithographically controlled wetting (LCW) using solutions of MMX polymers to produce conducting nanopatterns on surfaces. These structures can be used to contact other molecular systems (ie. the technique has already been used for the electrical characterization of pentacene semiconducting thin layers). Wet lithography procedure could be also use to contact the MMX nanowires.
