Ag‐dendrimer nanoclusters were prepared with Ag + and carboxyl shell (G4.5) poly(amino amine) dendrimers. Self‐assembly photosensitive ultrathin films were then fabricated with these Ag‐dendrimer nanoclusters as polyanions and diazoresin (DR) as polycation. With UV irradiating the films became stable because of the formation of covalent linkages between the layers. Compared to similar films containing no Ag nanoclusters, the obtained films showed greatly enhanced electric conductivity. © 2003 Wiley Periodicals, Inc. J Appl Polym Sci 89: 1515–1519, 2003
