Abstract
Absolute fluorescence quantum yields of trans-stilbene and all-trans a lpha, omega-diphenylpolyenes with the polyene double-bond number (n) f rom two to six have been determined in a room-temperature solvent. The 1(1)Bu-fluorescence yield measured as a function of the polyene chain length shows a maximum for n = 2, while the 2(1)Ag-fluorescence yield shows a maximum for n = 3, and both yields decrease with further incr ease of n. The observed quantum yield behavior is discussed briefly.
