Notes:
Static quenching performed on the type II cleavage of polyacrylophenone, poly(1-benzoylethylene), (PAP) in 1-methylnaphthalene, (MeN) as solvent and as quencher, has allowed us to evaluate the rate constant of electronic triplet-triplet energy transfer Kel for the system PAP-MeN.This value is similar with the value determinated for the system valerophenone-MeN. indicating that Kel is independant of the carbonyl position free or bound to a polymer chain.The aspect of the quenching curve at high concentration of MeN in benzene has been associated with phenomenona of preferential solvation of benzene in the ternary system PAP-MeN-benzene which has been determinated by the method of dialysis equilibrium.
