✦ Synopsis

Understanding how electrons travel through organic matter is important in designing materials for organic microelectronics [1] and understanding biological electron-transport processes. [2,3] Herein we describe a simple experimental procedure to measure rates of electron transport across organic thin films having a range of structures, compare the data for several types of films, and outline a theory appropriate for analyzing these rates. We use a junction that is particularly easy to assemble: M-SAM(1)SAM(2)-M' (Figure 1, ªSAMº is a self-assembled monolayer). [4, 5] We have
