摘要

Charge transfer interaction of a persistent perfluoroalkyl radical, perfluoro-3-ethyl-2,4-dimethyl-3-pentyl (PFR-1), with benzene and methyl substituted benzenes (toluene, m-xylene, mesitylene), 1-decene, and diethyl ether was investigated by UV-vis spectrophotometric measurement. It was found that the aromatic and oleflnic pi-electrons and also the unshared electron pair of ether can interact with the low-lying radical orbital of PFR-1 through CT complex formation. The Beer's law was confirmed in the range of 5-20 mM of PFR-1 for the aromatics and 5-40 mM for 1-decene and diethyl ether. The red shift of lambda(max) occurred with increasing number of methyl substituents on the benzene ring. (C) 2014 Elsevier B.V. All rights reserved.
