The synthesis and the characterization of new cyclic and polymeric pho
sphazenes with interesting applicative potential in the photochemical
domain is reported. In particular, cyclic and polyphosphazene derivati
ves containing 4-tert-butoxycarbonyloxyphenoxy (BOC) residues (5a-b),
cyclophosphazenes substituted with alpha,alpha'-dialkoxyacetophenone g
roups (6a-c) and bearing tertiary amines as side phosphorus substituen
ts (7a-b, 9a-b, 12 and 13) are described.
