Abstract: We report the self and spin-assembly of poly(2,5-methoxy-propyloxy sulfonate phenylene vinylene) (MPS-PPV) multilayer polyetectrolyte systems using poly(ethylenimine) and three poly(propylenimine) starburst dendrimers as polycations. These films are not stable over time if the assembly process terminates with MPS-PPV layer deposition. However, we were able to achieve temporal stability by terminating the assembly process after a spin-assembled dendriiner layer. We also show that the spin- assembly process provides a means of controlling the optical and photolurninescence properties of the multilayer systems. We have assembled films with a variety of photoluminescence properties. Emission maxima can be tuned from 550 to 590 nin by changing the concentration and number of bilayers. Furthermore, we have investigated the effect of a dendrimer layer of various generations and concentrations when assembled onto a single bilayer of generation 3 dendrimer and MPS-PPV. By controlling the concentration and generation we are able to produce films of a desired thickness and photoluminescence quantum efficiency. Bulk phase solution studies have been conducted to supplement this work and suggest strong interactions between the dendrimers of all generations and WS-PPV. The nature of this interaction is not yet understood.
