Long Distance Electron Transfer

这项研究的意义在于它与控制生物电子转移的特定因素的关系。本文描述了在先前的支持期间在罗切斯特设计和合成的新型分子内双卟啉系统中的电子转移实验。这些分子允许在供体-受体距离、角取向、桥接基团性质、介质动力学、反应自由能和反应重排能等方面有系统的变化。这样的研究可以为目前的电转移反应理论提供关键的检验。

The significance of this research is in its relationship to thespecific factors which control biological electron transfer. Experiments are described to study electron transfer in novelintramolecular bis porphyrin systems which have been designed andsynthesized at Rochester during the previous support period. These molecules allow systematic variations in donor acceptordistance, angular orientation, nature of bridging group, mediumdynamics, reaction free eneergy and reaction reorganizationenergy. Such studies can provide critical tests of currenttheories of electrotransfer reactions.
