Photochemical behavior of poly(organophosphazenes). IX. Internal photostabilization effects in (4-benzoylphenoxy)x (β-naphthoxy)2−x phosphazene copolymers
Abstract The synthesis and the photochemical behavior in solution and in films of a series of polyphosphazenes containing both benzophenone and naphthalene groups are described. The light energy absorbed by the benzophenone group is transferred to the naphthalene chromophore and wasted in photophysi...

| 520 | |a Abstract The synthesis and the photochemical behavior in solution and in films of a series of polyphosphazenes containing both benzophenone and naphthalene groups are described. The light energy absorbed by the benzophenone group is transferred to the naphthalene chromophore and wasted in photophysical processes which are not harmful to the polymer. This leads to a remarkable photostabilization of the benzophenone-containing phosphazene macromolecules, the extent of which is related to the amount of naphthalene substituents present in the copolymers. The naphthoxy groups directly bonded to the polyphosphazene backbone are more efficient photostabilizers than free naphthalene added to solutions or films of the benzophenone-substituted polyphosphazenes. This is the first example of photostabilization of a polyphosphazene achieved by an energy transfer process between the light-absorbing chromophore and an energy acceptor supported on the same inorganic$$\begin{array}{*{20}c} {} & | & {} \\ - & P & = \\ {} & | & {} \\ \end{array} N -$$ skeleton. | ||

| abstract |
Abstract The synthesis and the photochemical behavior in solution and in films of a series of polyphosphazenes containing both benzophenone and naphthalene groups are described. The light energy absorbed by the benzophenone group is transferred to the naphthalene chromophore and wasted in photophysical processes which are not harmful to the polymer. This leads to a remarkable photostabilization of the benzophenone-containing phosphazene macromolecules, the extent of which is related to the amount of naphthalene substituents present in the copolymers. The naphthoxy groups directly bonded to the polyphosphazene backbone are more efficient photostabilizers than free naphthalene added to solutions or films of the benzophenone-substituted polyphosphazenes. This is the first example of photostabilization of a polyphosphazene achieved by an energy transfer process between the light-absorbing chromophore and an energy acceptor supported on the same inorganic$$\begin{array}{*{20}c} {} & | & {} \\ - & P & = \\ {} & | & {} \\ \end{array} N -$$ skeleton. © Plenum Publishing Corporation 1991 |
