Efficient S_1-S_1 Radiationless Energy Transfer in Solid Cyclohexane and 1, 4-Dioxane Solutions at Unusually Low Concentration
Singlet-singlet radiationless energy transfer between 6,6′-bis(diethylamino)-2,2′-bipyridine (<B>1</B>) and 3,3′-dihydroxy-2,2′-bipyridine (<B>2</B>) was observed at unusually low concentration (3 × 10<SUP>−5</SUP> mol dm<SUP>−3</SUP> of <B>1</B> with 10 mol% of <B>2</B>) only in solid solutions of cyclohexane and 1,4-dioxane but not of methylcyclohexane, cyclohexanol, hexane, 3-methylpentane, cyclopentane, and tetrahydrofuran.
