then self-assembled on gold in the presence of selected alkanethiols in order to form mixed monolayers. The properties and electron transfer behavior of the monolayer assemblies were investigated using electrochemical methods. It was found that the rates of electron transfer through oligoglycine bridges decrease rapidly with distance only for short chain derivatives, while for the longer bridges the distance

氨酸桥的电子转移速率随着距离的增加而迅速降低,而对于较长的桥的距离依赖性较弱。肽桥二级结构的差异和电子转移机制的变化被认为是较长肽链观察到的速率常数增加的可能原因。
