Fluorescence quantum yields of α, ω-diphenylpolyenes
Absolute fluorescence quantum yields of trans-stilbene and all-trans α, ω-diphenylpolyenes with the polyene double-bond number (n) from two to six have been determined in a room-temperature solvent. The 11Bu-fluorescence yield measured as a function of the polyene chain length shows a maximum for n = 2, while the 21Ag-fluorescence yield shows a maximum for n = 3, and both yields decrease with further increase of n. The observed quantum yield behavior is discussed briefly.
