As functional elements in opto-electronic devices approach the singlemolecule limit, conducting organic molecular wires are the appropriate
interconnects that enable transport of charges and charge-like particles such as excitons within the device. Reproducible syntheses and a
thorough understanding of the underlying principles are therefore indispensable for applications like even smaller transistors, molecular
machines and light-harvesting materials. Bringing together experiment and theory to enable applications in real-life devices, this handbook
and ready reference provides essential information on how to control and direct charge transport. Readers can therefore obtain a balanced
view of charge and exciton transport, covering characterization techniques such as spectroscopy and current measurements together with quantitative models. Researchers are thus able to improve the performance of newly developed devices, while an additional overview of synthesis methods highlights ways of producing different organic wires. Written with the following market in mind: chemists, molecular
physicists, materials scientists and electrical engineers.

About the author (2011)

Laurens Siebbeles studied chemistry at the Free University in Amsterdam and obtained his PhD degree at the FOMInstitute for Atomic and Molecular Physics in Amsterdam. He was a post-doc at the University of Paris Sud in France. Currently he is Professor in opto-electronic materials at the Delft University of Technology in The Netherlands. He studies the dynamics of charges and excitons in molecular materials and semiconductor nanocrystals. Charges and excitons are produced with high-energy electron or laser pulses and probed by time-resolved optical and microwave or terahertz measurements. The experiments are supported by theory of charge and exciton dynamics.

Ferdinand Grozema studied chemistry at the University of Groningen and obtained his PhD degree at the Delft University of Technology. In 2007 he spent 7 months working as a visiting scholar at Northwestern University in Evanston, USA. Currently he is an Assistant Professor in the opto-electronic materials section at the Chemical Engineering Department of the Delft University of Technology in Delft. His research
interests consist of theoretical and experimental studies of the properties and dynamics of excited states in bio/organic materials. The main focus of this research has been on charge transport in conjugated molecular wires and in DNA.
