Popis:	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 olefinic π-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 λ max occurred with increasing number of methyl substituents on the benzene ring.
