Quantum yield of monomer fluorescence

The intrinsic quantum yield of monomer fluorescence QM for the polymer is the same as for the monochromophoric model compound. QM in air-equilibrated rigid hosts is the same as in degassed hydrocarbon solvents, and is independent of the host matrix in rigid systems. [Pg.80]

Braga, and Lumb (131,274), although criticized for its simplicity (125,283), accounts well for experimental decay of the singlet excimer. The observed quantum yield of monomer fluorescence is reduced in the presence of excimer from the intrinsic yield according to ... [Pg.197]

If is the quantum yield of monomer fluorescence and Ij, the intensity, and 1 the respective values of the excimer fluorescence and Oq and Iq those of the monofunctional derivative the following equations can be derived ... [Pg.375]

Reactions of this type can be studied by measuring the quantum yield of monomer fluorescence as a function of concentration. A simple kinetic analysis shows that the reaction scheme indicated above leads to the so-called Stern-Volmer relationship... [Pg.441]
